Russia bombarded Ukraine’s second-largest city with massive strikes in the early hours of Saturday, its mayor said, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Ukraine says that a large Russian drone-and-missile attack has targeted the eastern city of Kharkiv, killing at least three people and injuring 21.

Rachel Maddow explains how Ukraine's "Spiderweb" drone operation, which destroyed several Russian military planes, exposed a huge global nuclear vulnerability.

The attack injected some much-needed optimism into Ukraine, beleaguered by years of war and worn down by what many see as U.S. pressure to concede to Russian demands.

Russian and Ukrainian delegates met in Istanbul on Monday for their second set of direct peace talks, a day after Kyiv launched a shock drone attack on Russia’s nuclear-capable bombers, in an operation that President Volodymyr Zelensky said was a year and a half in the making.
