Moscow's warning to the UK comes after a wave of Ukrainian strikes on Russia.

In the latest attacks overnight, Russian officials said some 620 drones had been flown towards the region surrounding Moscow. Russian air defences destroyed more than 180 of the drones but several people were wounded, officials said.

In a statement, Wildberries said a logistics complex had "sustained minor damage" in the attack.

The overnight strikes inside Russia came amid a barrage of Russian missile and drone attacks on Ukraine.

In the deadliest attack, on Pechenihy in north-eastern Ukraine, private homes, a cafe and post office were hit, as two missiles claimed the lives of 10 villagers.

Elsewhere, three Ukrainians died in Sumy, two in Zaporizhzhia, two in Kherson. Five people were wounded in Izium close to the front line in the east and Kyiv came under five waves of attack overnight.

On Saturday night, Ukraine fired some 822 drones towards Russia, with 600 aiming for Moscow, according to its regional governor, who said the Russian capital had suffered "one of the most massive drone attacks in recent memory". Seven deaths were reported across Russia.

On the same night, Russian attacks on Ukraine killed at least seven people and injured more than 39.

In April, the MoD announced it would supply Ukraine tens of thousands of drones, including long-range strike devices, in its biggest ever package.
