A Russian drone attack on the Ukrainian city of Kharkiv on Friday damaged a maternity hospital, authorities said, terrifying patients as windows shattered and shards of glass fell on to the beds, leaving families rushing to shelter their babies.

Russia fired 597 drones and decoys, along with 26 cruise missiles, into Ukraine overnight into Saturday, Ukraine’s air force said. Of these, 319 drones and 25 cruise missiles were shot down, and 258 decoy drones were lost, likely having been electronically jammed.

Russia fired more than 620 drones and long-range missiles overnight, killing at least six people in the latest wave of strikes, Ukraine said Saturday, calling for fresh sanctions on Moscow
