A Ukrainian drone strike on an industrial city in Russia's Tatarstan region has killed at least 13 people, including a child, in one of the deadliest attacks of its kind since Moscow launched its war on Ukraine. The strike hit Nizhnekamsk, located about 750 miles inside Russia, and targeted an industrial center. Regional officials said 12 people were killed and 39 wounded, while other reports put the death toll at at least 13. The attack is among the highest civilian death tolls from drone strikes in Russia in recent months, as Ukraine seeks to disrupt Russia's oil supply. No further details were immediately available.
