Members of the US special forces have been disciplined after an investigation into the death of British aid worker Linda Norgrove in Afghanistan revealed she was killed by a grenade thrown by her would-be rescuers.
The 36-year-old from the Western Isles died in a blast in Kunar province on October 8 during a failed rescue attempt led by American forces.
Ms Norgrove, a former United Nations employee, was working for the firm Development Alternatives Inc (DAI) when she was captured in the Dewagal valley during an ambush on September 26.
Initial reports suggested she was killed when one of her captors detonated a suicide vest.
An investigation led by US Major General Joseph Votel and British Brigadier Robert Nitsch found that she died when a grenade was thrown into a gully.
Intelligence suggested the aid worker was being held in a group of buildings higher up the mountain and it was only when they returned that they found her body.
Reporting to the Commons, Foreign Secretary William Hague said that although US soldiers reported their use of a grenade, senior officers did not become aware until they examined video footage.
Mr Hague said: "The investigation team found that the failure to disclose information that a grenade was thrown breached US military law.
"As a result, members of the rescue team have been disciplined for failing to provide a complete and full account of their actions in accordance with US military procedure.
"I cannot announce any more details of the disciplinary action taken by the military of another nation, but the fact that this action has been taken will confirm to this House how seriously the US authorities regard this matter."
