LONDON: The parents of the Scottish aid worker Linda Norgrove have praised the US military for admitting one of its service members may have accidentally killed her – saying in a televised interview that the circumstances of the death could easily have been kept secret.

Ms Norgrove, 36, died in a botched attempt to free her following her kidnapping in the Kunar province of Afghanistan on September 26. Officials initially said her captors killed her, but the US general David Petraeus later acknowledged that she might have been killed by a US grenade.

In the interview, her parents refused to play what Ms Norgrove's mother, Lorna, called "the blame game

. . . Linda is dead and there's nothing going to bring her back to us".
