A Ukrainian drone attack at an industrial plant in central Russia has killed three people and injured 35 others, a Russian regional governor has said.

Three people have been killed and 35 taken to hospital following an attack by Ukraine on a factory in the city of Izhevsk - more than 1,000km (620 miles) from the border, Russian authorities say.

Ukraine has for months been using domestically produced long-range drones to strike plants, storage sites and logistical hubs deep inside Russian territory. In May last year, a Ukrainian drone hit an early-warning radar in the Russian city of Orsk, some 1,800 km from the Ukrainian border, Kyiv officials claimed.
