Officials stated that a Ukrainian drone strike on Russia's Tatarstan region, specifically the city of Nizhnekamsk, resulted in at least 13 deaths and 39 injuries. This marks one of the deadliest single attacks on Russia since the start of the war, with Moscow confirming industrial facilities and residential areas were targeted. Nizhnekamsk is over 1,100 kilometers from the Ukrainian border and hosts major oil refineries and a large petrochemical company.
