A U.S.-mediated ceasefire between Russia and Ukraine appeared under serious strain on its second day on Sunday, with both sides accusing the other of violating the deal through weekend attacks.
The three-day pause, announced on Friday by President Donald Trump, is part of a broader U.S.-led push for peace that has so far failed to end the more than 4-year-old war despite months of shuttle diplomacy.
Three people were killed in Russian drone strikes on areas near the front line, and more than 200 battlefield clashes had taken place since early Saturday, Ukrainian officials reported on Sunday.
