• Russia-Ukraine war: latest updates

Russian forces now control more than two-thirds of the key eastern Ukrainian city of Sievierodonetsk as Ukraine's president, Volodymyr Zelenskiy, conceded that Kyiv's forces were suffering up to 100 deaths and 500 wounded every day.

With fierce street fighting in Sievierodonetsk, western officials suggested that the city of Sloviansk was the likely next target for a Russian advance that has made gains in the past fortnight, even as the Biden administration announced it was sending advanced rocket systems to Kyiv.
