The airport in the Russian city of Kazan reopened on Saturday after temporarily closing earlier in the day following a Ukrainian drone attack, Russia's aviation watchdog said.
Russian state news agencies reported the drone attack on a residential complex and other areas in Kazan, some 800 kilometers east of Moscow.
The Defense Ministry said the city had been attacked by three waves of drones between 7:40 a.m. and 9:20 a.m. (0440 and 0620 GMT). It said three drones were destroyed by air defense systems and three others by electronic warfare systems.
There were no casualties reported, agencies said, citing local authorities. The mayor of Kazan said on Telegram that all planned mass events in the city would be canceled over the weekend and that authorities would offer temporary accommodation to evacuees.
The Baza Telegram channel, which is close to Russia's security services, published unverified video footage showing an aerial object crashing into a high-rise building, producing a large fireball.
Russian foreign ministry spokeswoman Maria Zakharova condemned the attack, saying Ukraine was "taking out its impotent anger for real military defeats on the peaceful population of Russia."
Airports in Izhevsk, a smaller city northeast of Kazan, and Saratov, some 650 kilometers south of Kazan, had also temporarily halted flight arrivals and departures, Russia's aviation watchdog Rosaviatsia said via Telegram.
Restrictions at the airports were later lifted, Rosaviatsia said.
