Russian forces pressed an offensive in eastern Ukraine on Friday, seeking to seize an advantage in the months before tanks pledged by Kyiv’s Western allies begin to arrive on the battlefield.

Ukrainian forces said on Friday they had repelled Russian attacks on Vuhledar and several other villages in the eastern Donetsk region over the preceding 24 hours. Russia also launched 148 attacks along the front line with Ukrainian forces in the southern Zaporizhzhia region over the past day using tanks, rockets and artillery, the regional military administration said.
