The reported strike comes two nights after the Security Service of Ukraine (SBU) and Ukraine's Special Operations Forces (SOS) launched a joint attack against the Ryazan Oil Refinery on Jan. 24. Locals reported sounds of explosions and an attempted drone attack on the refinery shortly before 1 a.m. on Jan. 26, the Russian Telegram news channel Astra said. Ryazan Oblast Governor Pavlo Malkov confirmed that Russian air defense units were repelling a drone attack in the region. Andrii Kovalenko, the counter-disinformation chief at Ukraine's National Security and Defense Council, posted video to his official Telegram channel purporting to show a fire at the refinery after it was hit by drones. The Kyiv Independent could not verify these claims at the time of publication.
