Bin Laden shot on sight, according to new SEAL book

Former SEAL Mark Bissonnette's description of the 2011 raid in Pakistan that left Osama bin Laden dead contradicts official accounts of how the terrorist leader met his doom.

Writing under the pseudonym Mark Owen in "No Easy Day," to be published next week, the anti-terror specialist says SEALS summarily shot bin Laden when he poked his head out of a door. Previous government statements held that bin Laden had ducked back into his room to retrieve a weapon when the team members shot him in the face.

The account may again raise questions over whether the raid was intended to capture or simply kill bin Laden, though Bissonnette says the SEALs were told to capture him if he surrendered.

White House spokesman Tommy Vietor would not comment on the conflicting accounts late Tuesday, according to published reports.
