Dec. 30 (Bloomberg) -- Eight American civilians were killed today in a suicide-bomb attack on a U.S. military base in Afghanistan, a U.S. official said.
A single attacker was responsible for the blast, which also caused an unspecified number of injuries, according to the official, who asked not to be identified.
A Pentagon spokeswoman, Lieutenant Colonel Almarah Belk, said the Americans died in an explosion at Forward Operating Base Chapman in Khost province. Belk said she didn’t know what installations or agencies are located at the base.
“We mourn the loss of life in this attack, and are withholding further details pending notification of next of kin,” State Department spokesman Ian Kelly said in an e-mailed statement.
The U.S. has been expanding the ranks of civilian aid experts in Afghanistan in parallel with the surge of military reinforcements aimed at the Taliban insurgency.
North Atlantic Treaty Organization forces spokesman Lieutenant Colonel Todd Vician said the explosion is under investigation.
Khost is located in eastern Afghanistan, along the border with Pakistan.
