Russian President Vladimir Putin acknowledged for the first time that "radical Islamists" were responsible for the attack on a concert hall outside Moscow.

Russia escalated its attacks on the Ukrainian capital after several weeks of halt, by launching several drone attacks on the Kyiv, Poltava and Cherkasy regions of Ukraine, Al Jazeera reported, citing Ukrainian officials.
