Pakistan Muslim League-Nawaz (PML-N) chief Nawaz Sharif on Thursday demanded the government form an independent commission to probe into the PNS Mehran base attack. “The government is not serious in probing the attack on PNS Mehran,” he said while talking to reporters at Islamabad airport. The PML-N leader was scheduled to leave for Nawabshah to condole the death of President Asif Ali Zardari’s father, but the flight could not take off due to bad weather. Nawaz said the attack on PNS Mehran base was “quite aggressive”, but the government does not appear seriously concerned about the matter. “We should have learnt a lesson from the Abbottabad incident and steps should have been taken to protect Pakistan’s sovereignty,” he said. The PML-N chief said the resolution passed by the joint sitting of parliament should not only be accepted, but implemented as well. Nawaz said independent probes should be launched into the Abbottabad operation and PNS Mehran attack. “If Pakistan wants to resolve matters itself, then it must adopt the practice of accountability,” he said. “Several generations of the nation are under heavy debt and it has now become necessary to break the beggar’s bowl,” Nawaz added.
