LVIV, Ukraine — As Russian forces appeared to retreat from parts of northern Ukraine, the Ukrainian military reclaimed territory there and — in one of its boldest moves since the war began five weeks ago — entered Russia for the first time and bombed a fuel depot.
With another round of peace talks underway, aid workers said an attempt to spirit a large convoy of civilians out of the shattered southern city of Mariupol had failed. The Ukrainian chapter of the International Committee of the Red Cross said it received permission from both sides of the conflict to enter Mariupol to evacuate people desperate to leave, but that it was forced to call off the rescue mission because it was too dangerous.
Ukraine’s rapid recovery of large chunks of its northern territory in recent days has sparked cautious optimism, although officials have warned citizens and soldiers to remain on guard.
