MOSCOW — Russian authorities say three children have died in a fire at a tent camp in the country’s Far East.

The cause of the fire that broke out early Tuesday in the camp has not been determined. Russian media say the camp, located in a ski area in the Khabarovsk region about 6,000 kilometers (3,700 miles) east of Moscow, housed 189 people at the time of the fire.

Russian news agencies quoted the regional governor’s spokeswoman, Nadezhda Tomchenko, as saying one child died at the scene and two more died in a hospital.

The children’s ages were not reported.
