Ukrainian drones hit Moscow's oil refinery for the second time this week, sending out flames and plumes of smoke over the south-eastern district of Kapotnya on Thursday morning. "Air defence forces are continuing to repel a large-scale attack. Several drones managed to reach the [Moscow oil refinery]," said Sergei Sobyanin, the city's mayor, adding that a shopping centre was also damaged. He claimed about 180 drones heading for the capital had been downed.
