U.S. forces in Iraq stormed a house in Baghdad on Monday and freed Egyptian telecommunications engineers kidnapped since Sunday, the head of their Egyptian parent company said. Naguib Sawiris, chairman of Egypt's Orascom Telecom, said U.S. forces raided a villa and freed two of the four Egyptians. The other two managed to escape on their own from a car they had been locked in, he added. "All four are free," Sawiris told Reuters by telephone from Algeria. More than 120 foreigners have been kidnapped in Iraq over the past year. Some have been released -- often following the payment of ransoms -- but around a third have been killed.
