Ukrainian drones have hit residential buildings in the Russian city of Kazan, more than 1,000 kilometres (600 miles) from the front line, bringing the war deep into the heart of Russia.
The Russian Ministry of Defence said the city, located some 800km (500 miles) east of Moscow, was attacked by three waves of drones between 7:40am and 9:20am (04:40 and 06:20 GMT) on Saturday.
