A former US Navy SEAL who helped take down Osama bin Laden in 2011 has broken cover, claiming he fired the fatal shot.
Robert O'Neill, 38, told The Washington Post on Thursday he shot bin Laden in the forehead.
Jihadists have reportedly issued a death threat against him following the revelation.
The former commando said he decided to come forward ahead of planned media appearances next week when his identity was disclosed by SOFREP, a website operated by former SEALs.
SOFREP's revelation was in protest at O'Neill's decision to reveal his role in the raid on bin Laden's hideout in the Pakistani garrison city of Abbottabad.

The highly decorated Montana native told the Post he was near the head of the column of US soldiers, adding that at least two other SEALs fired shots.
The newspaper said two SEAL team members had corroborated his identity.
In postings on Twitter and the al-Minbar Jihadi Media forum, pictures of O'Neill had been distributed and messages in Arabic and English urging revenge, said a group which monitors jihadist websites.
"One jihadist wrote in Arabic, for example, 'We will send the picture to the lone wolves in America, this Robert O'Neill, who killed Sheikh Usama bin Laden...'," SITE said.
Another posted in both languages said, "To our loved ones among the Muslims in the United States of America, this is your chance for Paradise, the width of which is the heavens and the earth," SITE added.
O'Neill is set to appear in a documentary on the Fox network next week.
At bin Laden's compound, O'Neill was located in the number two position for the attack.
Bin Laden briefly appeared at the door but the SEAL in front of O'Neill apparently missed his shot.
"I rolled past him into the room, just inside the doorway," O'Neill said.
"There was bin Laden, standing there. He had his hands on a woman's shoulders, pushing her ahead."
O'Neill said he could clearly identify bin Laden through his night-vision scope, despite the darkness - and fired.
The onetime SEAL said it was clear bin Laden was dead as his skull was split.
O'Neill is the second member of the elite unit involved in the bin Laden raid to go public, in a move which has dismayed military brass and serving SEALS who maintain a fierce, Omerta-like code of silence.
