WASHINGTON/ISLAMABAD: Al Qaeda’s operations chief in Pakistan and a top aide have been killed, Pakistani officials confirmed on Friday. Operations chief Osama Al-Kini was thought responsible for attacks including the bombing of Marriott hotel in Islamabad and an unsuccessful attempt to kill former prime minister Benazir Bhutto. Al-Kini and his lieutenant Sheikh Ahmed Salim Swedan, both Kenyans, were killed in a missile strike in South Waziristan on January 1. Security officials in Islamabad said Al-Kini’s killing would relieve the security apparatus of a ‘big worry’. agencies
