Bin Laden book No Easy Day 'contradicts official account'
A first-hand account of the May 2011 raid by US forces that killed Osama Bin Laden contradicts the official story, the Associated Press claims.
It has purchased an advance copy of an unauthorised account of the raid, No Easy Day, by a former Seal.
The book says Bin Laden was shot dead as soon as he looked out of his bedroom as Seals rushed up the stairs, AP says.
The BBC's Paul Adams reports from Washington.
