Overnight Ukrainian drones struck the Ust-Luga port in Leningrad region, starting a fire later claimed by the SBU as damage to five oil reservoirs and the Kalibr-capable ship Naro-Fominsk. Russia answered with strikes on energy infrastructure in eight oblasts, hitting six major substations and leaving parts of Kryvyi Rih without power.
Attention then moved to Abu Dhabi, where the second day of Ukraine-U.S.-Russia talks lasted under two hours and closed without agreement on territory. Kyiv rejected ceding Donbas and accused Moscow of misleading U.S. envoys about frontline control, a claim echoed in ISW assessments of wider Russian demands. A prisoner exchange was the only reported result, while U.S. envoys Kushner and Witkoff announced a trip to Moscow before meeting Zelensky.
Zelensky, speaking from Denmark and then Ireland, said Washington was seeking modifications on Donbas and held out a window for a deal by year-end.
