If these charges are true...this soldiers deserves to be hanged for treason: (CBS)_An American soldier is among three suspects being held in connection with a grenade and small-arms attack that injured at least 16 U.S. soldiers at Camp Pennsylvania in northern Kuwait, reports CBS News Correspondent Mark Strassman, who is on the scene with the Army's 101st Airborne Division. Eleven of the injured were hurt so seriously they had to be choppered out of the camp. Strassmann said three grenades were rolled into three officers' tents at the camp. When officers ran from the tents, they were hit by small arms fire. Three suspects were being held for questioning: two Kuwaitis who served as translators and an American soldier described as an engineering sergeant. The American was found injured and hiding in a bunker. Asked if he was hurt throwing a grenade, Strassman reports the soldier replied, "Yes." Separately, Strassmann reported, an Iraqi rocket fired at U.S. forces in Kuwait was destroyed by Patriot missiles launched from nearby Camp New Jersey. The attacks on U.S. troops came as the American assault on Iraq gained steam. American and British forces besieged the southern city of Basra and pounded Baghdad with impunity.
