As world powers talk about how to end the deadliest conflict in Europe since World War II 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.

Surgutneftegaz’s Kirishinefteorgsintez refinery, one of the top two refineries in Russia, was among the targets attacked by Ukrainian drones, Russian officials said.
