At least four killed as Russia and Ukraine trade overnight strikes — Odesa hit and Russia's Kirishi refinery set on fire
Overnight strikes between Russia and Ukraine killed at least four people and set fire to Russia's second-largest oil refinery. A Russian attack on the port city of Odesa killed three people, the head of the city's military administration said, and left one person seriously wounded. In Russia's Leningrad region, Governor Aleksandr Drozdenko said a Ukrainian drone attack set the Kirishi refinery on fire, and that a woman was killed by falling drone debris. Ukraine's energy officials said Russian attacks had left consumers without electricity across 12 regions.

Key points

- The Kirishi refinery, Russia's second-largest, was set on fire in a drone attack; Governor Drozdenko said 113 drones were downed.
- Russian attacks left consumers without electricity in 12 Ukrainian regions, Deputy Energy Minister Nekrasov said.
- Ukraine says Russia has attacked its energy sector 128 times in the past week.
What happened
Both sides have been targeting energy infrastructure through the autumn: Ukraine stepped up strikes on Russian refineries in late October after a US-announced energy ceasefire failed to take hold, and Russia has pressed its campaign against Ukraine's power system as winter approaches — over the weekend, strikes left more than 600,000 people without power in Dnipropetrovsk region alone.
The overnight exchange came a day before US-brokered talks between Russia, Ukraine and the United States open in Abu Dhabi, with European officials also attending.

What we know / what we don't know yet
What we know
- The four deaths and their sources: three in Odesa on the city administration's account, one in the Leningrad region on the governor's account.
- That the Kirishi refinery was set on fire and that power was cut across 12 Ukrainian regions, on officials' statements from both sides.
What we don't know yet
- The extent of the damage to the Kirishi refinery — neither report states it.
- Whether Ukraine hit the Morozov plant, and whether a Black Sea cargo ship was hit or carried arms — both claims are unverified in the reporting read.
Why it matters
The pattern is now the war's centre of gravity: refineries and power grids, hit nightly, with the costs landing on civilians in Odesa and Vsevolozhsk alike and on households across 12 Ukrainian regions facing winter without reliable power. The Abu Dhabi talks open against the heaviest week of energy attacks Ukraine says it has recorded.
