Ukrainian drones attacked the Russian city of Izhevsk on Tuesday, killing three people and wounding dozens in one of the deepest strikes inside Russia of the three-year conflict, authorities said.
Izhevsk, more than 1,000 kilometres (620 miles) from the front line, has arms production facilities including factories that make attack drones and the world-famous Kalashnikov rifle.
A Ukraine security services source said Kyiv had targeted an Izhevsk-based drone manufacturer and that the attack had disrupted Moscow’s “offensive potential”.
