Ukraine launches massive drone attack on Russia

(Reuters): Ukraine launched a large attack with at least 361 drones targeting Russia overnight, sparking a brief fire at the vast Kirishi oil refinery in Russia's northwest, Russian officials said on Sunday, reporting no injuries.

As world powers talk about how to end the deadliest conflict in Europe since World War Two the drone war has escalated, with Russian drones downed in NATO-member Poland and attacks by Ukraine against oil refineries and pipelines in Russia, the world's second biggest oil exporter.

Russia's defence ministry said at least 361 drones had been shot down by Russian air defence systems, including four guided aerial bombs and a US-made HIMARS missile. It did not give details about the location of the attacks.
