Omar, a Jordanian who became a U.S. citizen in 1986 came to Iraq, shortly after Saddam Hussein's ouster in 2003. US troops arrested him at his Baghdad home, allegedly finding guns and bomb parts. He was held for more than a year without charges or, he says, legal counsel, and he was handed to an Iraqi prison, according to the family. (AP Photo/Lefteris Pitarakis)
