KABUL, Afghanistan — The U.S. military says one of its soldiers was wounded when insurgents launched an attack in eastern Afghanistan’s remote Achin district of Nangarhar province.

Capt. Tom Gresback, a U.S. military spokesman in Afghanistan, told the Associated Press one U.S. service member was wounded and in stable condition in what he would describe only as “active ground engagement.” He refused to give further details including whether it involved a local militia.

In Afghanistan, local militias are often paid by the U.S. and are partnered with them in operations in remote regions.

The Taliban claimed the attack Thursday was carried out by two insurgent disguised as local militiamen. Taliban spokesman Zabiullah Mujahid told The Associated Press the attackers had infiltrated the local force months earlier.

Gresback said they were investigating the incident.
