U.S. troops may have killed kidnapped British aid worker during failed rescue attempt

U.S. and British officials are investigating whether a British aid worker kidnapped by Taliban militants in Afghanistan may have been inadvertently killed by American troops as they attempted to rescue her last week.

British officials initially announced that Linda Norgrove, 36, had been killed by her Islamist captors Friday during a rescue attempt carried out by U.S. special forces. Norgrove was kidnapped along with three Afghan colleagues two weeks ago in eastern Kunar province while visiting a development project there. Militants had earlier freed Norgrove’s Afghan co-workers.

On Monday, the U.S. military said in a statement that a review of surveillance footage and interviews with members of the rescue team “do not conclusively determine the cause of her death.” Gen. David H. Petraeus, commander of U.S. and NATO forces in Afghanistan, ordered an investigation into Norgrove’s death, the statement said.

In London, British Prime Minister David Cameron said at a news conference that Petraeus had told him that Norgrove may have been killed by a grenade thrown by a member of the U.S. rescue team. Cameron said his foreign secretary, William Hague, had given the go-ahead to launch the rescue effort after deciding that Norgrove was at grave risk. Cameron said Hague’s decision had his support.

“We were clear that Linda’s life was in grave danger and the operation offered the best chance of saving her life,” Cameron told reporters. “I will obviously go over in my mind 100 times whether it was the right decision, but I profoundly believe it was.”

President Obama called Cameron to offer his “deepest condolences,” the White House said.

A former United Nations worker, Norgrove was working on a $150-million project for the U.S. aid group Development Alternatives Inc., aimed at strengthening local economies in Afghanistan.

The decision to forge ahead with a rescue mission was made after North Atlantic Treaty Organization allies received a tip about Norgrove’s whereabouts. Six militants holding Norgrove were also killed in the rescue attempt.
