Kabul, Afghanistan (CNN) -- The bodies of two female aid workers were discovered Sunday morning in Afghanistan's Helmand province, a spokesman for Helmand's governor told CNN on Tuesday.
Daud Ahmadi said one of the women was the founder of the organization Mahjoba Herawi, an Afghan non-governmental organization. Ahmadi said both were working on women-oriented projects such as jam and pasta making.
The women's driver disappeared, and it was unclear whether robbers or the Taliban killed the women, Ahmadi said.
The deaths come after a British aid worker held hostage in eastern Afghanistan was killed by her captors during an October rescue attempt.
Linda Norgrove, 36, worked for DAI, an international humanitarian group. U.S. military officials have said investigations were underway to determine whether Norgrove was killed by a grenade thrown by American forces trying to free her.
Also in southern Afghanistan, a NATO-led service member died after an insurgent attack, NATO's International Security Assistance Force said. The force did not identify the nationality of the service member or precisely where the incident occurred.
