Coalition and Afghan forces killed a suspected Al-Qaeda member and detained 13 others in a raid on Tuesday on a residential compound in the southeastern province of Khost, the US military announced.
The troops killed the suspect when he tried to flee, disguised as a woman, during the raid in Ya'Qubi district, the military said in a statement.
"The purpose of this operation was to capture a known Al-Qaeda facilitator considered a significant threat to Afghan and coalition forces," it said.
The raid was conducted after "credible intelligence linked the targeted terrorist to weapons and explosive smuggling in the Khost province."
The forces seized detonators and other bombmaking materials. Around 60 women and children were also living in the compound.
"It is a known extremist tactic to surround themselves with women and children and put them in harms way," coalition spokesman Tom Collins said.
