Russian forces have launched a large-scale drone assault across Ukraine. Ukrainian officials said that the attacks overnight Wednesday killed three people and wounded 64 others.

The assault continued Moscow’s stepped-up drone and missile attacks, which have been ratcheting up for months with nightly bombardments on regions and cities in Ukraine.

A concentrated, nine-minute-long Russian drone attack on Ukraine's second largest city of Kharkiv in the middle of the night killed three people and injured 64, including nine children, Ukrainian officials said.
