A four-member CBS crew led by correspondent Bob Simon left behind cash, equipment and a Saddam Hussein wristwatch before apparently heading into occupied Kuwait, Saudi officials said Friday.

Simon, producer Peter Bluff, cameraman Roberto Alvarez and soundman Juan Caldera have been missing since Monday, CBS spokesman Tom Goodman said in New York."They should not have been there but we are obviously concerned and have alerted our forward posts to be looking," a Saudi military official said. U.S. military officials said they asked allied units to be on the lookout for the news crew.
