KYIV - Russia launched 805 drones and 13 missiles in an overnight attack on Ukraine, the Ukrainian Air Force said Sunday.

As of 8:30 am local time (0530 GMT) Sunday, the air defense had intercepted 747 combat and decoy drones, along with four Iskander-K cruise missiles, said the Ukrainian Air Force in a Facebook post.

Five additional Iskander-K missiles, four Iskander-M/KN-23 ballistic missiles, and 56 drones struck 37 locations across the country, it added.

Meanwhile, Ukrainian authorities said the Russian drone attacks triggered a fire in the country's government building and "emergency crews are working to extinguish the fire."

This has been the first time since the start of the Russia-Ukraine conflict that "the government building, including its roof and upper floors, was damaged in the attack," Prime Minister Yulia Svyrydenko confirmed on Telegram.
