The siege in Karachi's naval air station ended on Monday afternoon after more than 15 hours leaving 10 inlcuding 2 rangers dead and 20 others injured "The Naval Airbase PNS Mehran has been cleared from terrorists. The base is fully under operational control of the Pakistan Navy. Eight sailors and two rangers have been martyred while 20 have been injured including 2 rangers", Pakistan Navy spokesman Commodore Irfanul Haq said Tehrik-e- Taliban has claimed responsibility for the attack. In a statement, they said it was revenge for Osama bin Laden's killing. Reports suggest that five terrorists have been killed and seven others arrested. The identity of the arrested men is not known. These terrorists will be taken to an undisclosed location as their interrogation could provide vital clues into the attack. Some media reports also suggest that several terrorists have been killed and that 3-4 terrorists have committed suicide. Between 10-15 terrorists stormed three hangars at the Pakistan Naval Station Mehran, a strategic air base of the Pakistan Navy close to the Karachi airport, late on Sunday night and targeted aircraft and equipment. The terrorists used rocket propelled grenades to damage and destroy several warplanes including two P-3C Orions - recently acquired from the United States for anti-submarine and maritime surveillance operations Commandos of the Pakistan Navy and the elite Special Service Group (SSG) were deployed to flush out the militants. The militants apparently entered the Naval base and hangers through the Pakistan Air Force museum, a source said. "They took advantage of the fact that people at that time were leaving for home from the PAF museum inside the Faisal base," a source said. A private TV channel quoted witnesses as saying that they had heard up to five blasts. Heavy firing continued for over 20 minutes after the first blast occurred, following which there were reports of intermittent firing. Hundreds of paramilitary personnel surrounded the airbase while commandos from the army's elite Special Services Group were sent in to sweep the area. Footage on television showed ambulances rushing to the airbase. The high-security area where the attack occurred also houses the Pakistan Air Force's (PAF) Southern Air Command, Air War College and museum as well as PNS Mehran. Sunday's raid appeared to be the most serious against the military since October 2009, when militants attacked the army headquarters in Rawalpindi. They held dozens hostage in a 22-hour standoff that left 23 people dead, including nine militants.
