On Friday 22 March, Islamic State claimed its deadliest attack in Europe when gunmen affiliated with the group stormed into the Crocus City Hall on the outskirts of Moscow and opened fire on people attending a rock concert. More than 100 people were killed.
Russian police failed to thwart the attack despite warnings issued by the US to Moscow that extremist groups were plotting attacks in Russia. President Vladimir Putin has acknowledged the involvement of ‘radical Islamists’ but suggested Ukraine was involved, which Kyiv has rejected.
