TEHRAN, Young Journalists Club (YJC) -A 57-year-old woman died, emergency services chief Jorge Melendez said, while another woman, who officials had previously said was dead, was resuscitated in hospital and remains in serious condition.
Earlier, Salvador Sanchez Ceren, El Salvador's president, had said two people died, with 22 people injured.
Melendez said the cause of the fire was not known.
Video pictures showed one person jumping from the top of the building and landing heavily on a lower roof near the ground.
Emergency services officials said the man was in grave condition in hospital.
Emergency services spokesman Carlos Fuentes said a few people had also jumped from the fifth and sixth floors of the burning building, suffering injuries.
About 50 people were evacuated from the building and 25 people were taken to hospital for treatment for burns and smoke inhalation, Fuentes said.
The government sent in helicopters to rescue people in the ministry as video showed thick plumes of smoke streaming from the building.
Jose Alfaro, another spokesman for emergency services, said there was no one left trapped in the building.
