A missing Iranian scientist has turned up alive in Washington, D.C.

Shahram Amiri was working for Iran's nuclear agency. He is just one of several Iranians who disappeared or were assassinated in connection with the Islamic regime's nuclear program.

Amiri went missing after he made a pilgrimage to Saudi Arabia in 2009.

At the time, Iran accused the Saudis of kidnapping and turning him over to the United States. However, the U.S. denies that.

Iran says Amiri has taken refuge at the Pakistani embassy in Washington and wants to return home.

"We contacted the Pakistani embassy and they confirmed that Shahram Amiri has taken refuge there," the Islamic Republic News Agency, the state news agency quoted the unnamed official as saying on Tuesday. "Further details will be revealed soon."

Intelligence analysts said Amiri's disappearance is part of a shadow war to prevent Iran from developing nuclear bombs.
