story building collapsed in Tehran on Monday, killing at least three people, the Iranian capital's fire department said. Tehran prosecutor-general Saeed Mortazavi said around 20 construction workers were in the building at the time, suggesting the death toll could rise. He said the owners had been told to tear the building down after it started to collapse about a month ago and that the workers had been trying to salvage window frames and equipment. "When the building collapsed early this morning the entire workforce of around 20 were in it and so far no one has been rescued," Mortazavi told state radio. A Reuters witness said the building had collapsed into a heap of rubble. Rescue workers were trying to shift the debris while sniffer dogs searched for victims and survivors. "We have so far unearthed three bodies," said Behrouz Tashakkor, spokesman for Tehran's fire department. "How many more there are under the rubble, I don't know. We are continuing to remove the rubble."

The student news agency ISNA said Ali Bagheri, a senior Foreign Ministry official, had taken over from Javad Vaeedi, who served as the deputy in charge of international affairs for the policy body, the Supreme National Security Council.
