At least 18 people were killed early Thursday when Russia launched one of its largest overnight air assaults on Kyiv, bombarding the Ukrainian capital with hundreds of drones and dozens of missiles.

Multiple explosions shook buildings and ⁠reverberated across the capital throughout the night as thousands of residents rushed to bomb shelters and underground metro stations. It was the second-deadliest Russian attack on Kyiv so far this year.

"This night, Russia once again carried out a cynical, large-scale attack on Ukraine," Prime Minister Yulia ​Svyrydenko said on the Telegram app. "The enemy launched dozens of ballistic missiles. Kyiv was hit the hardest."

"As of now, ​18 ⁠people are known to have been killed."

President Volodymyr Zelenskyy had cut short a visit to Dublin Wednesday night and warned Ukrainians about the upcoming strike.
