August 6, 2023 Russia-Ukraine news

Our live coverage of Russia's war in Ukraine has moved here.

Ukrainian strikes inside Russia and Moscow-controlled territory are an increasingly common feature of the war, and Kyiv has effectively served notice that the attacks will continue, with President Volodymyr Zelensky declaring the conflict is "returning to Russia."

Here's what we know about some of the recent attacks:

Sunday's bridge strikes: Missiles rocked a pair of bridges linking occupied regions of Ukraine to the Crimean peninsula, which Moscow seized in 2014. Ukraine's military said the strikes "hit two key routes of communication" for Russia. Kyiv has made it clear that it will prioritize cutting off the annexed peninsula from land newly captured since Moscow's full-scale invasion of 2022.

Attacks at sea: Ukraine hit one of Russia's largest oil tankers with a sea drone late Friday, within 24 hours of an attack on a naval base in Russia's Black Sea port of Novorossiysk. The first assault left a Russian warship badly damaged. The attacks were carried out using an emerging Ukrainian tool: sea drones that can travel long distances and have proven difficult to defend.

Drones cross the border: A string of aerial drone strikes have also peppered Russian cities, including Moscow, throughout the summer. Though recent strikes on the Russian capital did not reportedly cause any injuries or fatalities — they have unsettled residents and created a sense that the scope of the conflict is drifting across the border. On Sunday, an attempted Ukrainian drone attack briefly halted traffic at an airport in Moscow, according to the city's mayor.

Ukraine says more is coming: Ukraine on Saturday pledged that there would be more attacks on Russian shipping in the Black Sea and another key bridge to Crimea — the structure linking the peninsula to mainland Russia, which Kyiv has also targeted on multiple occasions. Any explosions that happen on Russia's ships or bridges in the region are "an absolutely logical and effective step," the head of the Ukrainian Security Service said this week. If Russia wants such explosions to stop, he added, "they have the only option to do so — to leave the territorial waters of Ukraine and our land."

Delegations from various countries and organizations attending the Ukraine peace summit in Jeddah, Saudi Arabia, agreed to continue working together toward "achieving lasting peace in the region," Saudi state news reported Sunday, but no specific developments were revealed.

In statements Sunday, the head of Ukraine's presidential office called the talks "productive" and "extremely honest and open," while Russia's deputy foreign minister dismissed the talks as "doomed" to prevent meaningful developments.

Some context: The lack of any concrete resolutions announced after the talks does not come as a surprise, as officials had tempered expectations.

The meetings — which did not include representatives from Russia — were seen mostly as a means for laying out future frameworks. They were also viewed as a venue to potentially win support for Kyiv's peace proposals from beyond its core Western backers like the United States and United Kingdom: The meetings included representatives from developing countries and from world powers that have sought to project varying degrees of neutrality in the conflict, like China and India.

Ukraine and Russia remain publicly committed to prerequisites for direct negotiations that the other side finds unacceptable.

Ukraine's military has confirmed that it struck road bridges linking Crimea and Russian-occupied parts of southern Ukraine on Sunday.

The strikes "hit two key routes of communication" for Russia, the Chonhar bridge linking the Kherson region to Crimea and a smaller bridge to the peninsula from the Ukrainian town of Henichesk, the Armed Forces of Ukraine said on Telegram.

Russian-backed authorities and Russian state media had earlier reported that Kyiv was responsible for strikes on the bridges. The Russian-appointed head of occupied areas in the Kherson region accused Ukraine of using British-supplied Storm Shadow missiles in the attack.

Explosions on two bridges to Crimea Sunday were caused by Storm Shadow long-range missiles supplied to Ukraine by the United Kingdom, according to Vladimir Saldo, the Russian-appointed acting head of Kherson region.

Saldo said the two bridges were used by civilian and not military traffic, and that a rupture to a gas pipeline running alongside the bridge cut off supplies to 20,000 residents of the city of Henichesk in Kherson.

Saldo said the attack targeted civilians and did not impact military operations.

The Russia-backed leader said the missiles did not cause structural damage to the Chonhar bridge, which links the Kherson region and Crimea. The bridge is now closed to traffic, but Saldo predicted it would reopen by the end of the day.

CNN cannot independently verify Saldo's claims, and Ukraine has not immediately commented on the attacks.

About the Storm Shadow missiles: In May, the United Kingdom delivered multiple Storm Shadow cruise missiles to Ukraine, giving the nation a new long-range strike capability to use during the counteroffensive against Russian forces, senior Western officials said.

The Storm Shadow is a long-range cruise missile with stealth capabilities, jointly developed by the UK and France, which is typically launched from the air. With a firing range in excess of 250 kilometers (155 miles), it is just short of the 185-mile range capability of the US-made Army Tactical Missile Systems, or ATACMS, that Ukraine has long asked for.

The extended range gives Ukraine the ability to strike deep into Russian-held territory in eastern Ukraine.

Multiple explosions have been reported on critical road bridges linking Crimea with parts of the Russian-occupied Kherson region in Ukraine, according to Russian-installed officials.

A bridge connecting the Arabat Spit, which is located on Crimea's east coast, and the Ukrainian city of Henichesk was among the reported targets. Explosions have been heard in the city, according to an unofficial Telegram channel, RIA Melitopol.

Strikes also hit the Chonhar bridge, which links the Kherson region and Crimea, said Vladimir Rogov, a member of the Russian-installed government in Zaporizhzhia.

The Russian-appointed leader of occupied Kherson, Vladimir Saldo, said Ukraine fired 12 missiles at the Chonhar bridge and nine had been shot down.

Saldo claimed Kyiv used advanced British Storm Shadow missiles in the attack. He also said the strikes hit a village school, and that one civilian who was on the bridge at the time of the attack was wounded.

Saldo said officials were still sorting through details of the attack and the extent of the damage to the bridge, a gas pipeline and nearby towns.

The Russian-appointed head of Crimea, Sergey Aksyonov, also acknowledged the attack, saying on Telegram that a bridge for cars and trucks was damaged, and "repair work is already beginning."

CNN cannot independently verify the Russian officials' claims, and Ukraine has not immediately commented on the attack.

Key context: Russia annexed the peninsula of Crimea in 2014, in a move condemned by Ukraine and its allies as illegal under international law. Kyiv has vowed to retake Crimea along with the territory occupied by Russia since it launched its full-scale invasion in 2022.

Key bridges connect the peninsula to mainland Russia and to areas of Ukraine occupied by Moscow's troops, which are now controlled by Russia-installed leaders.

Crimean bridges have emerged as key targets in Ukrainian drone and missile attacks, especially as Ukraine vows to ramp up its assault on Russian targets in and around the Black Sea, and as Ukrainian President Volodymyr Zelensky says Kyiv's troops are working "to bring the war back where it came from."

A Russian guided aerial bomb struck a blood transfusion center in the country's northeastern Kharkiv region Saturday, according to Ukrainian President Volodymyr Zelensky.

He said on Telegram that there are dead and wounded victims as a result of the attack, but did not provide any specific numbers.

Zelensky said the blood transfusion center is located in the Kupyansk community, where Russia has recently amassed troops on the eastern front line. A fire broke out at the center following the attack, he added.

CNN cannot independently verify reports about attacks on the front lines in Ukraine.

The area was liberated in a Ukrainian counteroffensive last fall.

Flights at Moscow's Vnukovo International Airport were temporarily disrupted during a drone alert Sunday.

Citing the airport's press service, Russian state news agency TASS said flight restrictions began at 10:26 a.m. in the capital due to "reasons beyond the airport's control."

Nearly 30 flights were affected.

Separately, Moscow Mayor Sergei Sobyanin said a drone attempted to break through Moscow's air defenses at about 11 a.m. local time but was destroyed on approach.

The Russian defense ministry later said a drone attack at 11:27 a.m. local time was "thwarted."

The capital on alert: Drone attacks on Moscow and inside Russia have become increasingly common in recent weeks. Officials in Kyiv have warned of more to come.

The second meeting on restoring peace in Ukraine is taking place in Jeddah, Saudi Arabia, with more than 40 countries participating today.

A senior official from Ukrainian President Volodymyr Zelensky's office said the peace talks, so far, have been productive.

Yermak said all the participants demonstrated their countries' commitment to the principles of the UN Charter. He described the peace consultations as "very productive."

Among the participants are senior officials from the European Union, United States, Germany, United Kingdom, China, India, South Africa and Turkey.

Russia was not represented. 

The meeting is expected to continue through Sunday. 

More context: The talks involve Ukraine, Western nations and representatives from developing countries — some of whom have refused to take sides in the conflict. Host country Saudi Arabia is hoping the summit results in support for Kyiv's peace proposals from beyond its core Western backers.

The meetings are likely to center more around the talking stages rather than concrete steps towards peace, as Ukraine and Russia continue to express conditions that are unacceptable to the other. Despite all this, the conference is being closely watched.
