"The blaze broke out at Factory No9," a spokesperson for the Sverdlovsk Region’s emergency services said.
The fire has been put out. Emergency service sources said they could not comment on the blaze due to the nature of the facility.
"This is a military factory. We can’t comment. The employees of the factory themselves put out the fire before the emergency services arrived," the spokesperson said.
The factory is located 881 miles east of Moscow. It belongs to Uralvagonzavod, an umbrella corporation that builds equipment both for civilian and military use, including tanks.
