One of Pakistan's most senior militants may have been killed in a U.S. drone strike in South Waziristan. Locals say Ilyas Kashmiri was among nine people killed in a strike, but his death hasn't been confirmed by officials. Kashmiri is a key al Qaeda commander believed to be responsible for Mumbai-style attacks on military targets in Afghanistan, Pakistan, and India. He is believed to be behind the attack on the Mehran naval airbase in Karachi last month, in which six militants held off Pakistan's special forces for 15 hours. Kashmiri has been declared dead before—in September 2009, Pakistani intelligence said he had been killed in a drone strike in North Waziristan.
