ISLAMABAD, PAKISTAN:  A Pakistani policeman guards the Marriott hotel in Islamabad, 29 October 2004, following last night's explosion. The Pakistani government insisted that an electrical short circuit and not a terrorist bombing was the most likely cause of a powerful explosion which had left at least seven people injured, including three Italian businessmen and an American diplomat.
