Russia Bombs Donbas Cities as Thousands Flee and a Key Town Teeters

Russian forces are raining bombs and drones on 'fortress belt' cities like Sloviansk and Kramatorsk in Ukraine's Donbas region, causing thousands to flee. A Russian troop build-up also threatens Kostyantynivka — if it falls, Russian forces could push toward Ukraine's last remaining strongholds in the east. Ukraine, meanwhile, is escalating attacks on Crimea to create a new pressure point for Moscow.
