Russia plays down overnight strikes as its forces make incremental gains in Donbas and launch missiles at Kharkiv

Ukraine has carried out one of its biggest ever drone attacks on Russia, with videos showing a series of explosions and fires at power stations and refineries including in Moscow.

Russia’s defence ministry downplayed the overnight strikes. It said it had intercepted and destroyed 158 unmanned enemy aerial vehicles. These were shot down over 15 regions, it claimed.
