Russia launched a barrage of drones and ballistic missiles across broad swaths of Ukraine early Friday, killing at least three people and injuring dozens of others, days after Kyiv launched a daring raid on Moscow’s fleet of strategic bombers.

Kyiv, Ukraine — Russia bombarded six regions of Ukraine in one of its largest aerial attacks of the three-year war, Ukrainian officials said Friday. The nighttime assault lasted for hours and killed three emergency responders in the capital Kyiv, according to authorities.
