Russia unleashed a barrage of drones and missiles on Ukraine overnight into Sunday, killing at least four people, with Kyiv suffering the heaviest assault.

The US will provide Ukraine with new intelligence to help guide long-range missile and drone strikes on Russia’s energy infrastructure, a move that marks an escalation in Washington’s role in the war.

US officials say he is considering whether to allow Ukraine to acquire Tomahawk cruise missiles, which could strike Moscow and most of the European part of Russia with their range of 2,500km.
