Russia launched a massive attack on Ukraine overnight into Saturday with hundreds of drones, killing at least one person, part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Russian strikes killed at least seven people and injured 28 others in multiple regions over the past 24 hours, Ukrainian regional authorities said on July 19.

At least three people have died following another widespread air bombardment by Russia. Two people were killed in the eastern Dnipropetrovsk region, the regional governor, Sergiy Lysak, said, while a woman died of her injuries after being rescued from a burning apartment in Odesa, according to emergency services.
