Moscow Hit by 'Largest Ever' Drone Attack

A major oil refinery in Moscow was set on fire early Monday. Ukraine launched what officials call its largest drone attack on the Russian capital to date. The strike came as voting ended in Russia's parliamentary elections. The vote was widely seen as a managed process with no real opposition. Emergency crews responded to the blaze at the refinery. The full extent of the damage was not immediately clear. Russian officials reported the attack without giving details on casualties. Ukraine has not yet commented on the operation.
