Massive Russian strikes in Ukraine kill at least 31

Russia launched 122 missiles and a score of drones against Ukrainian targets, officials said Friday, killing at least 31 civilians across the country in what an air force official called the biggest aerial barrage of the war.

At least 160 people were injured and an unknown number were buried under rubble during the roughly 18-hour onslaught, Ukrainian officials said. A maternity hospital, apartment blocks and schools were among the buildings reported damaged across Ukraine.

The attacks - which also saw a Russian missile passing through Polish airspace-triggered international condemnation and calls for military support to Ukraine, which has been fighting off invading Russian troops for almost two years.

"Today Russia hit us with almost everything it has in its arsenal," President Volodymyr Zelensky said.
