A roadside bomb struck a U.S.-led coalition vehicle on Sunday, killing one service member and wounding another on the outskirts of the Afghan capital, a coalition spokesman said.
The blast happened in Hussein Kheil village, in Kabul's eastern outskirts on the way toward a police training center, said Bariyalay Khan, a district police chief.
Coalition spokesman 1st Lt. Nathan Perry confirmed the casualties but did not specify their nationalities.
Khan said those traveling in the convoy were Americans.
Najib Rahman, another police official at the site of the blast, said an American helicopter landed to pick up the wounded while another hovered overhead.
Militants regularly use roadside bombs to attack Afghan and foreign troops in the country, which is facing a Taliban-led insurgency.
More than 2,700 people — mostly militants — have been killed so far this year in insurgency-related violence, according to an Associated Press tally of figures from Afghan and Western officials.
