Russia's Emergency Ministry says 14 Vietnamese workers have been killed by fire at a clothing factory near Moscow.

The ministry said one Vietnamese man also was hospitalized with serious burns from the fire, which erupted Tuesday in the town of Yegoryevsk, 80 kilometers (50 miles) southeast of Moscow.

Investigators haven't yet determined the cause of the blaze.

Russia has a poor fire safety record, with about 12,000 fire deaths reported last year.

The country suffers frequent fires at hospitals, schools and other state-run facilities, many blamed on negligence and fire safety violations. Migrant workers, many of whom live and work in primitive conditions, often fall victim to such fires.
