Pakistan's military vowed Thursday to eliminate terrorism, undeterred by a call from al-Qaida chief Osama bin Laden for a rebellion against President Gen. Pervez Musharraf. "We have the aim and objective, as our national duty, to eliminate terrorists and eradicate extremism," army spokesman Maj.-Gen. Waheed Arshad said. "Such threats issued through videos or in any other way cannot deter us" from fulfilling that duty, Arshad said. In a new audiotape released Thursday, bin Laden said the Pakistan army's bloody siege of fighters holed up in Islamabad's Red Mosque made Musharraf an infidel.
