Russian forces have blown up a bridge linking the embattled Ukrainian city of Sievierodonetsk to another city across the river, cutting off a possible evacuation route for civilians, local officials said on Sunday.
Sievierodonetsk has become the epicenter of the battle for control over Ukraine's eastern Donbas region. Parts of the city have been pulverized in some of the bloodiest fighting since the Kremlin unleashed its invasion on Feb. 24.
