Volgograd airport introduced temporary restrictions on aircraft arrivals and departures between 7:47 PM and 8:45 PM UTC on October 26th, 2025, according to the Federal Air Transport Agency. This development occurred as over 1,700 subscribers in the Zaporizhzhia district lost electricity due to at least five enemy UAV strikes, which also damaged private homes, a sports facility, and farm buildings, according to the regional administration. In the Sumy region, media reported explosions in Konotop during the same period, prompting public warnings to exercise caution. Energy workers are awaiting security improvements to begin restoring power in Zaporizhzhia. The previous report from earlier in the day detailed a drone strike on the Belgorod Reservoir dam, causing significant flooding and threatening Russian military positions, alongside UAV activity and fires in the Moscow region. Earlier in the reporting window, between 5:47 PM and 6:45 PM UTC, the Belgorod Reservoir dam was damaged by a drone strike, leading to a 100 cm water level drop and posing a threat of inundation to Russian military units and nearby settlements. This incident was followed by visible flooding downstream from the dam, with satellite imagery showing submerged territories, as noted in previous reports. Simultaneously, the Moscow region experienced air defense activity and reported fires at an oil depot. Russian Foreign Minister Sergey Lavrov asserted on October 26th, 2025, that Russia has not violated the Budapest Memorandum, while Ukrenergo announced no power outages for household consumers on October 27th, 2025. Separately, six individuals received prison sentences in London for an arson attack on industrial premises in March 2024, linked to the "Wagner" group. Ukraine's President Zelensky announced that Ukraine would receive additional Mirage fighter jets and air defense missiles earlier in the day.
