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.

Russia launched over 30 missiles and 300 drones during its overnight assault that affected 10 regions of the country, Ukrainian President Zelenskiy said.

Russian air defense units intercepted 13 drones flying towards Moscow in under two hours, Mayor Sergey Sobyanin reported at around 1:46 a.m. local time on July 19.
