A military plane carrying dozens of journalists crashed into a Tehran apartment block and exploded yesterday, killing at least 116 people, officials said.

All 94 passengers and crew on the C-130 transport plane died, the Interior Ministry said. Several children, at home because schools were closed due to a smog alert in the capital, were among the dead in the building, witnesses added.

The Tehran Coroner's Office told the ISNA students news agency it had received 116 corpses. Twenty-eight people, some in critical condition, were taken to hospital.

"I was sitting at home when the windows suddenly smashed and flames came pouring in," a woman in her 50s with cuts on her neck, said. "There was smoke everywhere."

Iran's fire brigade chief Ahmad Ziaie told state television the building which was hit, located in a densely populated area of south Tehran, housed about 150 people. The crash occurred in the early afternoon.

"Both the main and reserve fuel tanks were full which is why the plane went up in flames as soon as it hit," he said.

The Air Force plane was bound for the Gulf port of Bandar Abbas. It was taking 68 local journalists to cover military exercises. Military personnel were also aboard. Minutes after take-off the pilot reported engine trouble and requested an emergency landing at Tehran's Mehrabad airport, but crashed just short of the runway, police said.

Iranian journalists at the scene wept and consoled one another over their colleagues' deaths.

"I was supposed to be on the plane as well so I don't know whether to be happy or sad," said a journalist from the ISNA students news agency who declined to be identified.

He said a colleague had called him from inside the plane before take-off. "He said that the pilot didn't want to fly because there was a technical problem with the plane."

State television showed footage of some of its employees killed in the crash accompanied by mournful music.
