Relentless Russian attacks on Ukrainian positions defending the strategically important eastern city of Chasiv Yar are disrupting troop rotations and the delivery of some supplies, soldiers in the area have said.

The Kremlin’s army is seeking to press its advantages in troop numbers and weaponry before Ukrainian forces are bulked up by promised new Western military aid that is already trickling in to the front line, analysts said.
