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.
Eight drones were used in the attack, according to the press service of the Tatarstan regional government. Six hit residential buildings, one hit an industrial facility and another was shot down over a river, it said in a statement.
Local authorities said there were no casualties. Ukraine did not acknowledge the attack in keeping with its security policy.
The Kazan airport temporarily halted flight arrivals and departures, Russia’s aviation watchdog Rosaviatsia said via Telegram.
The incident comes amid growingly brazen attacks after Russia’s President Vladimir Putin proposed a “high-tech duel” with Kyiv during his end-of-year news conference on Thursday, suggesting he would test his claims that Russia’s new hypersonic ballistic missile was impervious to air defences.
On Friday, at least one person was killed and seven were wounded after Russian hypersonic missiles hit Ukraine’s capital Kyiv.
