International News Article | Reuters.com: "NAJAF, Iraq (Reuters) - Aides to militant Iraqi cleric Moqtada al-Sadr blamed U.S. tank fire on Friday for three small holes that appeared in the vast gilded dome of Shi'ite Islam's holiest shrine, the Imam Ali mosque in Najaf.
Qais al-Khazali, Sadr's chief spokesman, showed the damage to journalists after six hours of heavy fighting in which U.S. armor advanced for the first time onto sacred ground in its confrontation with Sadr's Mehdi Army militia.
The holes, high above the ground, were on the side of the dome facing Najaf's vast cemetery, where U.S. tanks stormed in to attack guerrilla positions hidden among the tombs."

Is this justified or not?
