MOSCOW, Aug 10 (Reuters) - A Ukrainian drone strike killed at least 13 people, including Central Asian nationals and a child, and wounded 39 others in the Russian city of Nizhnekamsk, authorities said on Monday, one of the heaviest civilian tolls in Russia in months.
Ukraine's military said it had hit Tatneft's TANECO oil refinery in the Tatarstan region, about 800 km (497 miles) east of Moscow, adding that a fire was recorded at the facility.
