At least 13 people are dead and dozens more injured after Vladimir Putin unleashed a massive drone and missile strike on Ukraine overnight. The nine-hour aerial bombardment took place for a second night running despite planned prisoner exchanges taking place in the daytime.

At least seven people have been killed as Russian forces attacked Kyiv and other cities early this morning, officials said. Moscow and Kyiv have exchanged attacks as Russia said it faced a barrage of Ukrainian drones and intercepted or destroyed around 100 of the unmanned Ukrainian weapons including some aimed at Moscow.

In the heart of Moscow, the Kremlin's defenses are being tested like never before, as Ukraine punishes Putin for dismissing ceasefire negotiations.

Ukraine's 425th separate assault regiment said its troops trained "hundreds of hours" to shoot small arms from atop speeding off-road bikes.
