(AP) - Saddam Hussein's son-in-law and one of the toppled Iraqi leader's bodyguards surrendered to an Iraqi opposition group after returning from Syria, where they had gone into hiding, the group said Sunday. Separately, the U.S. military said troops captured a top science official from Saddam's regime: the minister of higher education and scientific research. The son-in-law, Jamal Mustafa Abdallah Sultan al-Tikriti, and the bodyguard returned from neighboring Syria to turn themselves in to the Iraqi National Congress in Baghdad, a congress spokesman in London said. The men could have information on the whereabouts of Saddam, the spokesman said.
