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 launched its largest drone and missile bombardment of Ukraine overnight into Wednesday, according to Ukrainian President Volodymyr Zelenskyy.

Russia fired a record 728 Shahed and decoy drones at Ukraine overnight, as well as 13 cruise and ballistic missiles, the Ukrainian air force said, in the latest escalation after weeks of mounting Russian aerial and ground attacks in the more than three-year war.

At least one person has been killed after Russia launched its largest drone attack on Ukraine since the beginning of its invasion, Ukrainian officials said Wednesday, just hours after US President Donald Trump pledged more military support for Kyiv and accused his Russian counterpart Vladimir Putin of throwing “bullsh*t” over peace talks.

I’m not happy,” Trump said after a call with Vladimir Putin, noting that he doesn’t believe the Russian leader is ready to end the war. “I’m very disappointed.”

President Trump is openly voicing his frustration with Vladimir Putin as Russia intensifies attacks while the U.S. tries to broker peace.
