Ukrainian authorities reported at least six people killed and 21 more injured across five oblasts as Russia continued its daily attacks on energy and other civil infrastructure. Russian strikes on 11 and early on 12 October hit the oblasts of Donetsk, Odesa, Kharkiv, Kherson, Sumy, Chernihiv and Zaporizhzhia, leaving some areas without electricity, water, and transport services.

Donetsk Oblast: Blackout, electric transport halted, casualties reported

On the morning of 12 October, Russians struck energy infrastructure in the Ukraine-controlled part of eastern Ukraine's Donetsk Oblast. The attack caused a complete blackout across multiple settlements. Head of the Donetsk Oblast Military Administration Vadym Filashkin said on Facebook that specialists began emergency repairs immediately. He noted that the full scale of the damage and restoration timeline remains unknown.

Vadym Liakh, head of the Sloviansk City Military Administration, said power outages disrupted the water supply in the city and forced trolleybus services to stop.

Ukrzaliznytsia reported that four trains were canceled due to the lack of voltage in the power grid. Reserve diesel locomotives were being prepared for four other trains, and two were delayed.

Filashkin also confirmed that Russian forces killed four civilians and injured nine more in Donetsk Oblast over the past 24 hours.

Odesa Oblast: Drone attack damages energy and civil infrastructure

Russian drones targeted Odesa Oblast last night. According to the head of the Odesa Oblast, Oleh Kiper, air defense units shot down most of the drones, but several reached their targets. One drone hit a gas infrastructure facility and an outdoor structure, causing fires that firefighters quickly extinguished. Another strike damaged an energy site and shattered windows at a district state administration building. One civilian was injured during the attack.

The city council of Bilhorod-Dnistrovskyi reported partial power outages and water supply disruptions in several neighborhoods. Communal workers and DTEK specialists were conducting repairs, with water supply expected to be restored by 12:30.

Kharkiv Oblast: Second night of drone strikes, five civilians affected

Russian forces attacked Kharkiv Oblast for the second consecutive night using Shahed-type drones. Around 01:00 on 12 October, four drones struck a school in Chuhuiv. The Kharkiv Oblast Prosecutor’s Office reported that the strike also damaged vehicles and broke windows in apartment buildings.

According to the head of the Kharkiv Oblast Military Administration, Oleh Syniehubov, Russian attacks caused acute stress reactions in five civilians—two women aged 59 and 78, two men aged 54 and 69, and a 12-year-old girl in Chuhuiv.

Russian forces also used seven Shahed-type drones and two FPV drones during the previous 24 hours to target five settlements in the oblast. Damage was reported at a school in Shevchenkove, an excavator in Pisky-Radkivski, and multiple buildings and vehicles in Chuhuiv and Bugaivka.
