Eight US civilians were killed by a suicide bomber in eastern Afghanistan on Wednesday, a US embassy official said.
The attack took place at Forward Operating Base Chapman in Khost province, in eastern Afghanistan, said the official, who declined to be named.
No US or Nato troops were injured in the blast, the official said.
The number of foreign civilians in Afghanistan is mushrooming as the war takes a turn away from concentrating on battlefield fighting amid a growing emphasis on development and aid.
As civilian teams arrive, they are being sent to provincial military bases, where many they are billeted to work alongside military reconstruction teams.
The attack on the Americans comes as the international forces in Afghanistan - numbering 113,000 and set to grow to 150,000 next year - are embroiled in controversy over the deaths of Afghan civilians in an operation on Saturday.
