Pakistani prime minister, defense chiefs to meet over U.S. airstrike January 13, 2012 -- Updated 0832 GMT (1632 HKT) Pakistan's prime minister is gathering the Cabinet's defense committee The committee will respond to a U.S. investigation into a deadly drone strike, an official says Pakistan's government has disputed the findings of a U.S. investigation Islamabad, Pakistan (CNN) -- Pakistan's prime minister is gathering the nation's top defense leaders together to respond to findings of a U.S. investigation into an airstrike that killed 24 Pakistani soldiers, a spokesman said Friday. The meeting set for Saturday is the first gathering of the Cabinet's defense committee since Prime Minister Yousuf Raza Gilani fired his defense secretary, a move that spiked tensions between the civilian government and its military. All Pakistani military service chiefs will attend the meeting, including the chief of the army, as well as the ministers of interior, defense and information, said Muhammed Akram Shaheedi, the prime minister's spokesman. Results of the U.S. investigation, which were released last month, found that its forces acted in self-defense on November 26 after being fired upon in Afghanistan, near the Pakistani border. Pakistan's government has formally disputed the findings of the U.S. investigation, saying the bombardment went on long after it reported its troops were under fire. The meeting also follows reports the United States launched its first drone strike this week in more than a month, targeting suspected militants in Pakistan's volatile tribal region that borders Afghanistan. The drone fired two missiles Tuesday at a suspected militant compound near the provincial capital of Miranshah in North Waziristan. Pakistan did not authorize the recent drone strike nor has it ever granted such permission to the United States, said Abdul Basit, a spokesman for the Pakistani foreign ministry. The meeting Saturday also provides Gilani with an opportunity to dial back tensions with his defense chiefs, which escalated after he fired Naeem Khalid Lodhi for what state media reported was "gross misconduct and illegal action." The firing followed a warning of "grievous consequences" by Pakistan's military, which made the threat in a statement following a Gilani interview in The People's Daily Online of China.
