Russia-Ukraine War: A Ukrainian drone strike on Russia's Tatarstan region killed at least 12 people and injured dozens on Monday, according to regional authorities. Reports say it is one of the deadliest single attacks carried out by Kyiv since the war began more than four years ago.

Kyiv confirmed it struck the city of Nizhnekamsk, situated more than 1,000 kilometres (620 miles) from the Ukrainian border. Located in Tatarstan, a major energy-producing region, the area houses key oil refineries that have repeatedly been targeted in Ukrainian retaliatory strikes.
