Earlier, the governor of the Omsk region, Vitaly Khotsenko, said an industrial zone had been hit by drones, without giving further details.

Ukraine, which is under heavy missile and drone attack from Russia, is conducting its own campaign of long-range drone strikes against military, energy and commercial targets, in an effort to raise the cost to Moscow of continuing the war.
