Ukraine launched a significant drone attack on Moscow, targeting a major oil refinery for the second time this week. The assault also caused disruptions to commercial flights at Moscow’s airports. Russian officials reported the incident on Thursday, characterizing it as one of the largest drone attacks since the start of the full-scale invasion in 2022. The attack occurred shortly after Ukrainian President Volodymyr Zelenskyy indicated he had been in discussions regarding bolstering Ukraine’s defense capabilities. This latest strike signals a potential escalation in Ukraine’s strategy to directly target Russian territory. The extent of the damage to the refinery and the duration of flight disruptions remain unclear.
