A rocket attack on a train station in the eastern Ukrainian city of Kramatorsk killed dozens as civilians raced to flee the Donbas region bracing for a feared Russian offensive. World leaders condemned the attack with US President Joe Biden accusing Russia of being behind an "horrific atrocity" and French President Emmanuel Macron called it a "crime against humanity". Fifty people were killed, including five children, the regional governor of Donetsk, Pavlo Kyrylenko, said as the toll rose on one of the deadliest strikes of the six-week-old war.
