MOSCOW — A fire at a textile workshop in Moscow has killed 12 people, including three children, officials said.
The victims were not identified but were reportedly immigrants.
The Investigative Committee, the top state investigative agency, said the fire broke out late Saturday in northeastern Moscow, damaging more than 32,000 square feet of the structure.
Investigators said they are looking at negligence or arson as possible causes.
Russia’s children’s rights ombudsman, Pavel Astakhov, said Sunday on his Twitter account that three children were among those who died, including a baby. He said the victims were migrant workers who lived next to their workplace.
Several dozen fire engines responded to the blaze, and it took firefighters about five hours to extinguish the blaze.
Investigators continued to sift through the rubble Sunday for evidence.
Many immigrants work in Russian factories, some of which have been investigated for hazardous working conditions. In April, a blaze on the outskirts of Moscow killed 17 migrant workers.
