Russia launched a new barrage of drones and missiles in an overnight attack on Ukraine on Saturday, targeting the west of the country and killing at least two people in the city of Chernivtsi on the border with Romania.

Ukrainian officials say Russia has fired more than 700 attack and decoy drones at Ukraine overnight. That tops previous nightly barrages for the third time in two weeks.

The latest assault included more drones in a single night than Russia used in the entire month of July last year.
