France lifted its terror alert to its highest level on Sunday, after ISIS claimed responsibility for the concert hall attack in Moscow that killed at least 137 people on Friday.
“Given the Islamic State's claim of responsibility for the attack and the threats weighing on our country, we have decided to raise the Vigipirate posture to its highest level: attack emergency,” French Prime Minister Gabriel Attal said in a post on X.
France’s decision to raise the alert came after a meeting of its defense and national security council, according to Attal.
On Monday, Attal said two attempted terror attacks on French soil had been foiled since January and 45 in total since 2017. He said thousands more soldiers were ready to boost its counter-terrorism force, should they be needed.
Speaking to reporters in Paris, Attal said that 4,000 soldiers were on standby to mobilize if necessary "in the event of an alert," in addition to the current 3,000 soldiers deployed across the country. Police presence in front of sites deemed sensitive such as schools would also be reinforced," he added.
