Authorities on Monday probed suspected links between radicals from the captured Red Mosque and militants in Pakistan's northwest frontier, where 73 people died in weekend suicide attacks and bombings. Interior Minister Aftab Khan Sherpao said the government was investigating whether the dramatic escalation of violence in the northwest was related to the Islamabad mosque. Sherpao, speaking to Geo television news, did not elaborate, according to a report of the Associated Press.
