KABUL, Afghanistan — Gunmen riding on a motorcycle opened fire and killed two Finnish women aid workers in the western Afghan city of Herat on Thursday, officials said, the latest in a series of attacks on foreign civilians that has rattled aid workers, contractors and journalists.
The two women were riding in a taxi when they were shot dead, said Sami Wafa, the chief of staff of the Herat governor. Herat police spokesman Raouf Ahmadi said the taxi driver had been detained as part of the investigation.
Finland's Foreign Ministry confirmed two Finnish citizens have died in Afghanistan on Thursday. Spokesman Keijo Norvanto said they worked for the International Assistance Mission, an aid group which has been operating in Afghanistan since 1966. The organization could not immediately be reached for comment.
"We are faced with a great tragedy," Finland's Prime Minister Alexander Stubb said in a statement. "Finland requires that a thorough investigation be conducted to bring those guilty to justice. Finland must also reassess the security situation in Afghanistan."
Militants carry out near-daily attacks in Afghanistan, usually targeting security forces, which have struggled to secure the country as foreign troops have been gradually withdrawn.
