Units of the Ukrainian Defense Forces damaged three drilling rigs of the Lukoil corporation in the Caspian Sea—V. Filanovsky, Yuri Korchagin, and Valery Grayfer—between 1:16 p.m. and 2:15 p.m. UTC on January 11, 2026, as part of measures to reduce Russia's military and economic potential, according to the General Staff of the Armed Forces of Ukraine. These platforms support the Russian occupation army, with fixed hits recorded and damage being clarified. The General Staff reported that defense forces also destroyed a launcher of a Buk-M3 anti-aircraft missile system in the area of Baranycheve settlement in temporarily occupied Luhansk Oblast, where hits and explosions were recorded, and struck a material and technical support unit of Russia's 49th Army near Novotroitske in temporarily occupied Kherson Oblast to reduce enemy logistical and combat capabilities. Ukraine's Air Force reported launches of KAB glide bombs in Donetsk Oblast during the same period. Separately, new UAVs continued flying one by one through Chernihiv Oblast toward Rivne Oblast past northern regions, according to Твій Чернігів. In Kyiv, all city boiler houses are operational and 85% of houses left without heating from recent Russian attacks now have heat, with further work underway to eliminate shelling consequences, as stated by Kuleba and posted by Оперативний ЗСУ. This follows earlier restorations of electricity to thousands of families in Kyiv Oblast, as reported by local officials.
