Russian forces have launched a large-scale drone assault across Ukraine, where officials said three people were killed and 64 others wounded.

A concentrated, nine-minute-long Russian drone attack on Ukraine's second-largest city of Kharkiv on Wednesday killed six people and injured 64, including nine children, Ukrainian officials said. The attack followed Russia's two biggest air assaults of the war on Ukraine this week,

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.
