Osama bin Laden, the founder and head of the Islamist militant group al-Qaeda, was killed in Pakistan on May 2, 2011, shortly after 1:00 am PKT (20:00 UTC, May 1) by United States Navy SEALs of the U.S. Naval Special Warfare Development Group (also known as DEVGRU or SEAL Team Six). The operation, code-named Operation Neptune Spear, was carried out in a Central Intelligence Agency-led operation. In addition to DEVGRU, participating units included the U.S. Army Special Operations Command's 160th Special Operations Aviation Regiment (Airborne) and CIA operatives. The raid on bin Laden's compound in Abbottabad, Pakistan, was launched from Afghanistan. U.S. military officials said that after the raid, U.S. forces took bin Laden's body to Afghanistan for identification, then buried him at sea within 24 hours of his death in accordance with Islamic tradition. According to a Pakistani official, the United States had direct evidence that Inter-Services Intelligence (ISI) chief, Lt. Gen. Ahmad Shuja Pasha, knew of bin Laden’s presence in Abbottabad.
