Russia launched its biggest ever drone attack on Ukraine on Monday night and Tuesday morning, sending a reported 188 drones into the country against various targets, resulting in power cuts in part of western Ukraine and damage to residential buildings outside Kyiv.

Russian forces are pushing hard along the frontline in the east of the country, amid uncertainty as to how the dynamics of the war might change once Donald Trump takes office in January. Russia also vowed “retaliatory actions” for fresh Ukrainian strikes on military targets inside Russia that used long-range missiles sent by the US.

Ukraine’s air force said 76 of the drones had been shot down overnight, as air defences struggled to cope with the massed attacks that have become common in recent weeks. “Unfortunately, there were hits to critical infrastructure facilities, and private and apartment buildings were damaged in several regions due to the massive drone attack,” the air force said in a statement.
