Russian air defenses engaged unmanned aerial vehicles over Novokuibyshevsk in the Samara region amid an ongoing attack targeting two oil refineries, with a first effective hit reported, according to Exilenova+ and Radar VRV Telegram channels during the 59 minutes ending 11:15 PM UTC on January 1, 2026. Exilenova+ stated the attack on the Samara region continued, with UAVs probably targeting the Novokuibyshevskyi and Kuibyshevskyi refineries, while Radar VRV specifically noted air defense work against UAVs in Novokuibyshevsk. Separately, the MYROSHNYKOV Telegram channel reported Ukrainian forces completed clearing operations in Kupyansk, where up to 1,500 residents remained, some having hidden Russian occupiers, as the enemy unsuccessfully attempted storms north of Kindrashivka and near Golubivka during the same period. Frontlinekit posted on X during a live space that those embezzling funds meant for Ukrainian soldiers deserve hanging, reiterating a statement made that night amid reports of corruption. These developments follow Russian air defense operations against UAVs over Novomoskovsk in the Tula region earlier on January 1, per the previous Radar Tula Telegram report.
