Vladimir Putin vowed to bring more “destruction” to Ukraine in retaliation for a drone attack on a central Russian home to key Kremlin weapons factories.

On Saturday, footage showed a drone striking a high-rise luxury apartment block and producing a large fireball in Kazan, which is located 500 miles east of Moscow. 

Ukrainian officials have not commented on the strike but said that Kyiv’s drones had hit a factory described as the “backbone” of Russia’s military-industrial complex because it produces fuel for missiles.

The city of Kazan also houses a new Kremlin factory that produces thousands of drones under licence from Iran, which are then fired at Ukraine.
