Ukraine drone strike on oil refinery deep inside Russia kills at least 13

Attack hundreds of miles from border one of deadliest launched by Kyiv as it steps up campaign to weaken Moscow’s economy

A “massive” Ukrainian drone strike on an industrial city deep inside Russia killed at least 13 people, according to the local mayor, as Kyiv steps up its campaign of long-range strikes on targets far from the frontline.

Kyiv said it hit the Taneko refinery in the industrial city of Nizhnekamsk, around 1,200km (750 miles) from the Ukrainian border. The raid was part of a campaign to reduce the “military potential of the Russian aggressor,” Ukraine’s general staff said. Footage circulating online appeared to show smoke rising from the refinery in the city.
