KIEV, Sept. 7 (Xinhua) -- Russia launched 805 drones and 13 missiles in an overnight attack on Ukraine, the Ukrainian Air Force said Sunday.

As of 8:30 a.m. 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.

Svyrydenko added that apart from Kiev, Russian strikes hit the cities of Kryvyi Rih, Dnipro, Kremenchuk and Odesa.

According to the State Service for Emergencies, a mother and her 2-month-old baby were killed in the capital, while more than 20 people were injured. ■
