More than three years into Russia's full-scale invasion, Ukrainians across the country retreat each night to bomb shelters and metro stations in a nightly ritual.

Moscow barreled hundreds of drones toward four key regions in Ukraine overnight, just as lawmakers in Kyiv scrambled to approve additional defense spending against the backdrop of intensified Russian attacks over the past few days.

Russian drones and missiles hit Kyiv in a barrage killing 31 and collapsing an apartment block. Three dead were children, ages 3, 6, and 17. About 159 injured.
