Britain's defense ministry said on Saturday that Russian forces were targeting civilians, a day after a missile attack on a train station crowded with women, children and the elderly killed at least 52 people, according to Ukrainian officials.
Russia was focusing its offensive, which included cruise missiles launched by its naval forces, on the eastern Donbas region, the British ministry said in a daily briefing.
It said it expected air attacks would increase in the south and east as Russia seeks to establish a land bridge between Crimea, which Moscow annexed in 2014, and Donbas but Ukrainian forces were thwarting the advance.
