Here's the latest

Strait of Hormuz: Iran’s navy says it has prevented US ships entering the Strait of Hormuz, according to state media, after President Donald Trump said the US military would help guide stranded vessels today. An Iranian official earlier threatened “any foreign military force” attempting to enter the strait.

• Seized ship to be returned: Separately, an Iranian ship seized by the US will be returned and the crew repatriated, according to Pakistan’s foreign ministry. Pakistan, a key mediator in peace talks, described the move as “a confidence-building measure” by the US.

• State of negotiations: Trump said his representatives “are having very positive discussions” with Iran. The Iranian Foreign Ministry said it was reviewing the US’ reply to its latest peace proposal.

US military denies claim that Iran struck US naval vessel

US Central Command has denied claims from Iranian state media that a US vessel was struck by Iranian missiles near the Strait of Hormuz.

“No U.S. Navy ships have been struck,” CENTCOM said in a post on X.

State news agency IRNA had reported, citing a military statement, that “following a firm and rapid warning by its navy, the entry of what it described as U.S. and Israeli enemy destroyers into the Strait of Hormuz was prevented.”

Iranian state media recently reported that Iran’s navy has prevented the entry of “enemy destroyers” into the Strait of Hormuz, after President Donald Trump announced the US military would begin protecting shipping trying to leave the Gulf.

If you’re just joining us, here’s what else we’ve been reporting on today:

  • The Strait of Hormuz has remained almost empty so far today, despite Trump’s announcement about the US guiding stranded vessels.
  • Oil prices fell in early trade after the Trump announced the plan to guide boats out of the Strait of Hormuz, but then steadied as traders took a wait-and-see approach to whether the plan would work.
  • Crew members from an Iranian ship seized by the US last month have been transferred to Pakistan for repatriation, according to Pakistan’s foreign ministry.
  • The Iranian Nobel Peace Prize laureate Narges Mohammadi is in critical condition after being transferred to hospital from prison last week, with her family saying the Iranian regime has so far not allowed her to be treated at a specialist care centre.

Kuwaiti crude oil exports fell to zero in April, with Hormuz effectively shut

Kuwaiti crude oil exports tumbled from more than one million barrels a day to zero in April, according to Iranian media, marking the “first such disruption” since the end of the Gulf War in 1991.

The Gulf nation pumped oil throughout the month, but authorities moved some of the production to storage and allocated a portion to refined products, the Iranian Students’ News Agency (ISNA) reported Monday, citing data shared by the oil tracking platform TankerTracker.

Shipments of refined fuels “continued in limited volumes even as crude oil shipments dropped to zero,” ISNA said, highlighting a “sharp break from its usual export flow of more than one million barrels per day.”

Just on Sunday, several regional nations including Kuwait announced a boost to oil production targets despite the effective closure of the Strait of Hormuz. The oil cartel OPEC said Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman would raise output by an extra 188,000 barrels a day. The announcement came days after the UAE announced plans to leave the group in a blow to members.

Last month, oil output from the Middle East took a nosedive as parallel blockades imposed by the US and Iran on non-allied vessels in the Strait of Hormuz stemmed exports.

Iran claims to have prevented US ships from entering Hormuz

Iran’s navy has prevented the entry of “enemy destroyers” into the Strait of Hormuz, the state news agency IRNA claimed Monday.

Citing a military statement, IRNA reported that “following a firm and rapid warning by its navy, the entry of what it described as U.S. and Israeli enemy destroyers into the Strait of Hormuz was prevented.”

CNN has reached out to US Central Command (CENTCOM) and the White House for a response to the claim.

CENTCOM has said its forces will begin restoring freedom of navigation for commercial shipping through the Strait of Hormuz on Monday.

“Our support for this defensive mission is essential to regional security and the global economy as we also maintain the naval blockade,” said Adm. Brad Cooper, CENTCOM commander.

Nearly a month since the ceasefire began, here's how US-Iran talks have developed

It is coming up to one month since the US and Iran first agreed to a ceasefire.

Here’s a look at what has happened with talks between Tehran and Washington since then:

UN warns aid crisis worsens as Iran war doubles delivery costs, cutting relief to refugees

The Iran war is deepening the refugee crisis with less aid reaching Sudan and Lebanon while transportation costs surge, due to disruptions along the Strait of Hormuz, a spokesperson for the United Nations warned.

“The Middle East crisis and the disruptions around the Strait of Hormuz are having devastating and far-reaching ripple effects on global supply chains, but also on aid delivery, which is getting slower and more expensive,” said Carlotta Wolf.

“Every dollar extra that we spend on transportation of aid is a dollar less that goes directly to the people forced to flee that the UN serves on the ground every day,” she told CNN’s Rosemary Church.

In Sudan, where there is an ongoing civil war displacing over 14 million people according to the UN, transportation costs “have doubled in price” while supplies being cut by a half, “going from 927,000 to over 1.87 million,” Wolf added.

Furthermore, the UN have only been able to support around 20% of the 1 million internally displaced in Lebanon, as Israeli strikes strain an already fragile ceasefire with Iran-backed Hezbollah.

“Even with the current ceasefire, some people are thinking about trying to return home, but many are returning to nothing. There is utter destruction and really, they need sustained support and humanitarian assistance to be able to survive and live with dignity,” Wolf said.

Hormuz empty of shipping as Iran and US compete for control

The Iranian Revolutionary Guard Corps (IRGC) map declaring Iranian military control over a wide area either side of the chokepoint.

The Strait of Hormuz remained almost empty Monday, despite US President Donald Trump’s announcement that the United States military would begin protecting shipping trying to leave the Gulf.

Shipping data sites showed one sanctioned tanker – the Botswana-flagged Nooh Gas – transiting the Strait on Monday. No other tankers or cargo ships were shown moving through the Strait at 5 a.m. ET.

Iran has rejected Trump’s plan to guide ships through, warning that “any foreign military force, especially the invading American army” will be attacked if they try to approach or enter the Strait of Hormuz.

Maj. Gen. Ali Abdollahi, spokesman for the unified command of Iran’s armed forces, said Iran will protect the security of the strait “with full strength” after the US pledged to guide stranded ships through the oil shipping chokepoint.

Iran’s foreign ministry said the US was unable to get out of its “self-made quagmire.”

Baghaie added that Iran and Oman, whose coastline is on the southern side of the Strait, were continuing talks on the management of the waterway. The two countries have “a shared responsibility to maintain the safety of maritime traffic in this strategic waterway,” Baghaei said.

Oman has not commented.

At the same time, the Iranian Revolutionary Guard Corps (IRGC) published a map declaring Iranian military control over a wide area either side of the chokepoint.

Family of Nobel laureate in critical condition says Tehran is refusing her necessary care

Narges Mohammadi sits in her apartment in Tehran on January 23, 2025.

The Iranian Nobel Peace Prize laureate Narges Mohammadi is in critical condition after being transferred to a hospital from prison last week, with her family saying the Iranian regime has so far not allowed her to be treated at a specialist care centre.

The Narges Foundation, run by Mohammadi’s family, said on Friday that she was transferred to a hospital in the Zanjan province after “a catastrophic deterioration in her health.” She remains at the cardiac care unit of that hospital, the family said.

Mohammadi’s family and supporters, as well as the Norwegian Nobel Committee, have urged Tehran to allow her to be cared for by specialists.

The family said her treatment at the hospital in Zanjan was focused on attempts to stabilize her heart rate and blood pressure through oxygen therapy.

“This does not constitute a comprehensive treatment process,” the foundation said in a statement over the weekend.

“Effective treatment for Narges Mohammadi’s conditions is only possible if she is transferred to her medical team in Tehran,” it said, adding that she needs proper assessment and a treatment plan based on her medical history.

Jørgen Watne Frydnes, the chair of the Norwegian Nobel Committee, called on Iran to allow the treatment, saying in a statement that Mohammadi’s “life is now in the hands of the Iranian authorities.”

Oil prices briefly dip on US plan to guide ships out of Strait of Hormuz

Oil prices fell in early trade after the White House announced a plan to guide boats out of the choked Strait of Hormuz, but then steadied as traders took a wait-and-see approach to whether the plan would work.

Brent crude futures for July, the global benchmark, were down 0.7% at $108.97 per barrel at 4.25 a.m. ET. West Texas Intermediate futures, the US benchmark, decreased by 0.62% to $97.14 a barrel.

US President Donald Trump announced the plan, dubbed “Project Freedom”, on Sunday, as fraught discussions to end the hostilities with Iran roll on. The US military will use a flurry of arsenal and thousands of service members to free vessels stuck in the Strait, according to CENTCOM.

Tehran immediately rebuffed the measure, warning that any “foreign military force” will be attacked if they try to enter the channel, according to a senior military official.

Meanwhile, officials in Tehran are reviewing the US response to their 14-point proposal submitted last week. Until now, efforts to bring both parties back to the negotiating table have failed over key sticking points – including the US’ demand that Tehran surrender its nuclear stockpile and Iran’s demands that the US lift crippling economic sanctions and pay reparations for its recent attacks.

US-seized Iranian ship and its crew to be returned to Iran, Pakistani officials say

Crew members from an Iranian ship seized by the US after trying to breach its military blockade last month have been transferred to Pakistan for repatriation, according to Pakistan’s foreign ministry.

Twenty-two crew members held aboard the M/V Touska container ship were taken to Pakistan Sunday night and will be handed over to Iranian authorities Monday, the ministry said in a statement Monday.

“The Iranian ship will also be backloaded to Pakistani territorial waters for return to its original owners after necessary repairs,” the statement said.

Pakistan described the move as “a confidence-building measure” by the US, and said the repatriation is being coordinated with the support of both the US and Iran.

US forces fired on and seized the Iranian-flagged M/V Touska on April 19 after it tried to get past the US naval blockade and ignored six hours of warnings, US Central Command previously said.

Iran warns foreign military "will be attacked" if they try to enter Strait of Hormuz

Iran has warned that “any foreign military force, especially the invading American army … will be attacked” if they try to approach or enter the Strait of Hormuz, according to a top military official.

Maj. Gen. Ali Abdollahi, the commander of Iran’s Khatam al-Anbiya Central Headquarters, the unified command of Iran’s armed forces, said Iran will protect the security of the strait “with full strength” in statement on Monday after the US pledged to guide stranded ships through the oil shipping chokepoint.

The waterway is under the control of Iran’s armed forces and any “aggressive action by America to disrupt the situation will only result in further complication and endangerment of the security of vessels” in the area, Abdollahi added.

US' Strait of Hormuz plan likely meant to make commercial ships "feel safe," expert says

People sit at the shoreline as boats navigate the Strait of Hormuz on Qeshm Island, Iran, on April 28, 2026.

The US plan to “guide” ships through the Strait of Hormuz leaves a lot of unanswered questions about how it would work just hours before President Donald Trump said it will go into effect.

US Central Command said in a statement on X that its support for the operations “will include guided-missile destroyers, over 100 land and sea-based aircraft, multi-domain unmanned platforms.”

How they figure into the ship movement is not defined.

Jennifer Parker, a nonresident fellow at the Lowy Institute and a former Royal Australian Navy officer, told CNN Monday that she expects the US military to increase its presence in and over the strait to provide reassurance to commercial vessels attempting to transit it.

“This appears to be an operation … which is less about providing direct protection to a vessel or a couple of vessels and more about trying to change the situation in the strait” so ships “feel safe,” Parker said.

That could include a few US Navy ships in the strait and a range of aircraft flying over it that could spot and take out any small boats or ships trying to attack commercial vessels, she said.

Why the Strait of Hormuz is vital to global energy supplies

A narrow waterway that bypasses Iran and Oman, the Strait of Hormuz is the main route for shipping crude from oil-rich countries such as Saudi Arabia and Kuwait to the rest of the world.

The strait has remained a crucial factor since the start of the conflict after it was effectively closed by Tehran. In recent days, it has seen just a handful of crossings, according to Kpler and other shipping data sources.

Iran controls the strait’s northern side. About 20 million barrels of oil, or about one-fifth of daily global production, used to flow through the strait every day, according to the US Energy Information Administration, which calls the channel a “critical oil chokepoint.”

According to the EIA, “very few alternative options exist to move oil out of the strait if it is closed.”

The strait also carries about one-fifth of global trade in liquefied natural gas.

Unfinished Iran war could give Xi the upper hand in Trump talks, sources say

Chinese President Xi Jinping speaks during a meeting at the Great Hall of the People in Beijing, China, on April 15, 2026.

China remains committed to the upcoming meeting between its leader Xi Jinping and US President Donald Trump regardless of the situation in the Middle East, and cautiously views its adversary’s months-long conflict with Iran as having potentially strengthened its negotiating position, according to Chinese sources familiar with the matter.

The rare in-person meeting, already once delayed due to the US-Israeli war with Iran, is now scheduled for May 14-15, according to the White House. Several sources indicate Beijing views the high-stakes summit as a singular opportunity to secure a more stable long-term relationship with its largest economic and military competitor.

But despite the perceived advantage, sources said Beijing remains extremely cautious, with opinion among government insiders split as to how to navigate the myriad complications unleashed by the conflict, not least the prospect of the Strait of Hormuz – through which China imports about a third of its oil and gas – remaining closed when Trump arrives in the Chinese capital.

Trump’s visit “is not the same as any other heads-of-state visit,” said a Chinese source under the condition of anonymity due to the sensitivity of the matter. “Trump’s time in office is likely to have a lasting impact on the world order and has already fundamentally altered how the US views its own interests.”

New York City drivers are voicing their frustrations with rising gas prices, telling CNN the war in Iran has led to pain at the pump.

“Us getting involved in a stupid war, I think that’s had, obviously, a direct effect on the cost of everything here,” Jeff Olson told CNN. “We’re only putting small amounts of gas in at a time in the hopes that the prices are going to come down again soon.”

On Sunday, national average gas prices jumped to $4.45 a gallon, up by nearly 50% since the war started.

Here's how US military may use its assets to guide ships through Strait of Hormuz

Arleigh Burke-class guided-missile destroyer USS Pinckney (DDG 91) conducts blockade operations on April 17.

The US plan to guide ships through the Strait of Hormuz will involve guided-missile destroyers, more than 100 aircraft, multi-domain unmanned platforms and some 15,000 service members, US Central Command (CENTCOM) said.

Here’s how those assets might be employed:

Guided-missile destroyers – Arleigh Burke-class warships are the workhorses of the US fleet, and as of April 24, the US had 12 destroyers in the Middle East, CNN has reported.

Some have been used to enforce the blockade of Iranian ports, but those operations have taken place outside of the strait in the Arabian Sea.

Since the war began, CENTCOM has only publicized two destroyers entering the strait to begin paving the way for minesweeping operations.

Destroyers are also the primary air defense for aircraft carrier strike groups, so not all of these warships in the region are likely to be used for duty in the strait.

Analysts do not expect the destroyers to be escorting merchant ship convoys through the strait.

100 aircraft – The US maintains a range of carrier- and land-based aircraft in the region. Armed helicopters could fly over ships going through the strait to take out any small boats attempting to block passages. US Air Force A-10 attack jets could also be used to hit targets on the water or missile batteries ashore.

Multi-domain unmanned platforms – These could include aerial and marine drones that could move with ships through the strait or be in the vicinity of it to react to any threats to merchant ships. The drones could be armed or just for observation or reconnaissance, depending on the platform and its setup.

15,000 service members – While this seems like a large commitment of troops, most are likely in support roles and not actually deployed in the strait. There are at least two US aircraft carriers in the region whose air assets could be used over the strait. Each of those carriers has around 5,000 personnel aboard.

Hear from one of thousands of sailors stranded in Strait of Hormuz

It’s estimated that about 20,000 seafarers are stranded in the waters of the Strait of Hormuz. CNN’s Isobel Yeung spoke to Captain Istique Alam, who mans an Emirati oil tanker that has been stuck off the coast of Oman for over two months.

Shipping executives cautious on US plan to guide ships through Strait of Hormuz

Ships and boats in the Strait of Hormuz seen from Musandam, Oman, on May 1, 2026.

Shipping executives are expressing caution over Project Freedom, the US operation starting Monday to guide trapped neutral ships through the Strait of Hormuz.

“It takes both sides to unblock — not just one,” said Bjørn Højgaard, CEO of ship manager Anglo-Eastern. “Either party can signal that they are willing to let certain ships through, but unless the other side accepts that in practice, it doesn’t materially change the reality on the water.”

“Announcements are one thing — safe and predictable passage is another.”

“The Chairman of Iran’s parliamentary National Security Commission has said such moves ‘will be considered a violation of the ceasefire.’ Under these circumstances we should be cautious,” said Richard Hext, Chairman of the Hong Kong Shipowners Association.

The stated objective of the US operation is to “restore freedom of navigation.”

In a statement, CENTCOM Commander Brad Cooper said: “Our support for this defensive mission is essential to regional security and the global economy as we also maintain the naval blockade.”

Project Freedom involves guided-missile destroyers, more than 100 land- and sea-based aircraft and 15,000 service members.

A US official told CNN the operation to guide ships through the strait is not an escort mission.

It’s not clear how the operation would work nor which countries the operation would help.

Before Project Freedom was announced, a tanker was reportedly hit by unknown projectiles in the Strait of Hormuz. According to UKMTO, all crew were reported safe.

The incident underscores the risk to all vessels when transiting the critical waterway.

US President Donald Trump called Project Freedom a “humanitarian gesture.”

Since the war broke out on February 28, hundreds of ships and an estimated 20,000 seafarers have been trapped inside the Gulf.

The crisis has also created shortages of food, medical supplies and water aboard some vessels, forcing crews to ration supplies while managing fatigue and mental distress.

The US plans to "guide" ships through Strait of Hormuz. Here's what to know

A cargo boat navigates the sea on April 28, 2026 on Qeshm Island, Iran in the Strait of Hormuz.

US forces will begin guiding ships through the Strait of Hormuz today in an effort a US official said is not an escort mission.

President Donald Trump announced the effort on Sunday, saying that “countries from all over the World, almost all of which are not involved in the Middle Eastern dispute” have asked the US to free up ships “locked up” in the key strait.

US Central Command said it “will support merchant vessels seeking to freely transit through the essential international trade corridor.”

Senior Iranian official Ebrahim Azizi has warned that any US interference in the strait would be considered a violation of the ceasefire.

Here are other key developments:

Crew safe after ship hit by projectile in Strait of Hormuz, maritime agency says

A vessel was reportedly hit by unknown projectiles in the Strait of Hormuz, the UK Maritime Trade Operations Centre said on Monday.

A map from the maritime authority showed the stuck vessel was located just off the northern tip of Oman’s Musandam Peninsula.

The strike was reported Sunday, before President Donald Trump’s announcement that US Central Command forces would begin guiding ships through the strait.

“All crew reported safe. No environmental impact reported. Authorities are investigating,” the UKMTO said on X.

Vessels are advised to transit with caution, it added.

Also on Sunday, a bulk carrier sailing near the coast of Iran reported being “attacked by multiple small craft,” according to the UKMTO.

The incident was reported around 11:30 a.m. UTC (7:30 a.m. ET) about 11 nautical miles west of Sirik, Iran. The crew of the vessel were reported safe and no environmental impact of the attack was reported, the UKMTO said.

The UKMTO did not state which country the vessel is registered with.
