At least 13 people have been killed in a Ukrainian drone strike on the Russian republic of Tatarstan, officials have said. One child was among the victims with 75 more people injured, Russian authorities said, in one of the deadliest single attacks on Russia since the start of Moscow's full-scale war in Ukraine.Kyiv has not yet commented on the strike on the city of Nizhnekamsk, which is more than 1,100 kilometres (680m) from the Ukrainian border.Ukraine's Armed Forces confirmed Nizhnekamsk's Tanevo oil refinery had been hit, while Ukrainian defence technology manufacturer FirePoint said its FP-1 drones had been used in the attack. The strike lasted several hours overnight and into the morning, local sources say. Unverified images on social media show large plumes of smoke and flames rising into the sky in daytime, with air raid sirens howling in the background. Although there is no official information yet on the target of the attack, Kyiv has recently stepped up its strikes on facilities it says contribute revenue and logistics to Russia's war on Ukraine.Moscow confirmed industrial facilities were targeted as well as residential areas. "Civilian individuals who were not involved in any military operations were present," Russia's Investigative Committee said. The BBC has not independently verified this information.
