Linda Norgrove was seized in the province of Kunar on 26 September

“The US commander in Afghanistan, Gen David Petraeus, has ordered an investigation into the death of a British aid worker held hostage.

Linda Norgrove’s death on Friday as US forces tried to rescue her was initially blamed on her Afghan captors.

But Prime Minister David Cameron said she may have been accidentally killed by a US grenade.”
