Saudi arms dealer Adnan Khashoggi has died at the age of 81. He had Parkinson's disease, according to his family.
Khashoggi was rumored to have been one of the world's richest men at the height of his career in the 1970s, when he was believed to have been worth some $4 billion.
He made his fortune by brokering international arms deals, and was implicated in the Iran-Contra affair, a notorious arms-for-hostages deal that saw several U.S. officials selling arms to Iran despite an arms embargo, and using the money to fund the rebel movement in Nicaragua.
