The death toll from Russia's deadliest single attack on Ukraine this year has risen to 38, President Volodymyr Zelenskyy said, after a strike on an ammunition warehouse west of Kyiv on Friday night triggered massive explosions and fires that engulfed dozens of nearby homes. Four people remain missing and 20 were injured, including two children, as emergency crews continue extinguishing fires and clearing explosives at the site in the village of Myla. The attack comes amid a wider escalation, with Russia's defence ministry warning it will launch "massive strikes" on Ukraine's energy grid in retaliation for Ukrainian drone attacks on Russian oil refineries and the retailer Wildberries, raising fears of a harsh winter for Ukrainians.

Russia said it downed almost 500 Ukrainian drones overnight, while unconfirmed reports suggested Ukrainian strikes had set fire to a major oil refinery in Kirishi, near St Petersburg, with 62 drones reportedly shot down over the surrounding region. Separately, at least three people were injured in a Russian drone strike on Kyiv on Saturday night, which sparked fires in a residential tower and several other districts; Russia claimed it had targeted a Kyiv factory allegedly storing explosives. Kremlin spokesman Dmitry Peskov vowed "an appropriate response" to what he called Ukraine's escalation, framing Moscow's strikes as targeting military and war-related infrastructure.
