(AP Photo/Massoud Hossaini) (Newser) – A man wearing an Afghan army uniform killed a US servicemember and an American civilian in the capital Kabul on Wednesday, NATO and an Afghan official say. A NATO statement says another US service member and two US civilians were wounded in the attack and were in a stable condition, reports the AP. A spokesman for the Afghan defense ministry says the attack took place inside a military base. The ministry has launched an investigation, he says. The NATO statement notes the attacker was later killed. "Anytime we lose a member of our team, it is deeply painful," the statement quotes the commander of US ForcesAfghanistan as saying. "Our sympathies go out to the families, loved ones, and the units of those involved." The victims were conducting duties as part of the larger NATO mission to train and advise the Afghan security services, and an investigation is being conducted to determine the exact circumstances of the incident. In May, two Romanian soldiers were shot and killed when two Afghan army recruits opened fire on them in southern Kandahar province. Both attackers were later killed.
