KYIV, Ukraine (AP) — Russia fired more than 700 attack and decoy drones at Ukraine overnight, topping previous nightly barrages for the third time in two weeks, part of Moscow’s intensifying aerial and ground assault in the three-year war, Ukrainian officials said Wednesday.

Ukraine said it struck a Russian air base on Saturday, while Russia continued to attack Ukraine with hundreds of drones overnight as 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 its largest drone attack of the war on Ukraine overnight into Wednesday, according to Ukrainian President Volodymyr Zelenskyy, with 741 aerial attack vehicles used in the bombardment.
