Moscow, 21 December 2024 (dpa/MIA) - A Ukrainian drone attack hit several residential buildings in the city of Kazan, located more than 800 kilometres from the Russian capital Moscow, Russian authorities said on Saturday.

The city announced on Telegram that the attack caused fires and no initial information on casualties was available.

Major weekend events were cancelled for security reasons and air traffic at Kazan's airport, the capital of the Russian republic of Tatarstan, have been temporarily suspended, officials said.

The drone attacks occurred in three waves and from different directions, the defence ministry wrote on Telegram.

It accuses Ukraine of attacking civilian infrastructure. Three drones were destroyed and three were repelled, it added.

According to the aviation authority Rosaviation, the regional airports of Izhevsk and Saratov have also temporarily suspended take-offs and landings for security reasons. These restrictions usually last for a few hours.

Ukraine, with Western support, has been defending itself against Russia's full-scale invasion for nearly three years and frequently targets Russian sites as part of its counteroffensive.
