At least five people died in a home that caught fire in a central neighborhood in the Salvadoran capital, firefighters said Monday.

"Regrettably five people died" in the blaze, which began late Sunday night, fire chief Abner Hurtado told reporters.

He said that none of the victims had been identified yet, adding that one of them was "a minor."

Living in the destroyed house were several low-income families, said Hurtado, without providing any further information about injuries among the residents.

The victims evidently were street vendors in downtown San Salvador, according to media accounts.

Hurtado added that firefighters are investigating the cause of the blaze, which was facilitated by the wooden structure of the house and the zinc sheets used in its construction.

Personnel with the medical examiner's office came to the site of the fire to examine the victims, authorities said. EFE
