A British aid worker held hostage in eastern Afghanistan since late last month was killed by her captors during a rescue attempt on Friday night, officials said.
Linda Norgrove, 36, worked for DAI, an agency that provides various services to developing nations. Norgrove managed projects for farmers and rural workers.
James Boomgard, DAI president and chief executive officer, called the news "devastating" and said his operation is "saddened beyond words by the death of a wonderful woman whose sole purpose in Afghanistan was to do good."
British Foreign Secretary William Hague said in a written statement that his forces received information about where she was held and "decided that, given the danger she was facing, her best chance of safe release was to act on that information."
"Responsibility for this tragic outcome rests squarely with the hostage takers," Hague said.
Norgrove was being held by two Taliban commanders, Mullah Basir and Mullah Keftan, who were both killed in the raid, an Afghan intelligence official said.
