Russian forces tightened their grip on the eastern Ukrainian city of Sievierodonetsk and cut off the last routes for evacuating citizens, a Ukrainian official said on Monday - a scene that echoed Moscow's assault on Mariupol last month.
Amid heavy Russian bombardment, regional governor Sergei Gaidai said on social media that all bridges out of the city had been destroyed, making it impossible to bring in humanitarian cargoes or evacuate citizens.
