KABUL, Afghanistan — An attacker wearing an Afghan army uniform opened fire on international troops Sunday in southern Afghanistan, killing one, NATO said. Coalition forces returned fire and killed the attacker.
The shooting was the latest in a string of attacks against U.S. and other foreign forces by their Afghan partners or assailants posing as them.
The alliance did not provide more details, saying an investigation was under way. It also did not disclose the nationality of the service member killed. NATO usually waits for member nations to provide those details.
Such attacks have raised the level of mistrust and ill will between the U.S.-led coalition and its Afghan counterparts and drawn concern about the readiness of government forces to take over their own security ahead of the 2014 deadline for the withdrawal of foreign combat troops.
The insider threat to foreigners trying to mentor and strengthen Afghan security forces has existed for years but has grown more deadly.
The U.S.-led coalition routinely reports each time an American or other foreign soldier is killed by an Afghan in uniform, but the military is under-reporting the number of overall attacks. The Associated Press reported earlier this month that the International Security Assistance Force, or ISAF, does not report attacks in which the Afghan wounds — or misses — his U.S. or allied target. It also doesn’t report the wounding of troops who were attacked alongside those who were killed.
The number of such attacks have been on the rise. So far this year there have been 18 attacks killing 11 soldiers, compared to 21 last year killing 35 coalition service members, according to NATO figures.
That compares with 11 fatal attacks and 20 deaths the previous year. In 2007 and 2008 there were a combined total of four attacks and four deaths.
U.S. officials say that in most cases the Afghans who turn their guns on their allies are motivated not by sympathy for the Taliban or on orders from insurgents, but rather act as a result of personal grievances against the coalition.
Also Sunday, a NATO service member was killed by a bomb in eastern Afghanistan.
The coalition initially said three service members were killed in the attack, but later corrected its statement.
Militants commonly plant bombs along roads used by security forces, inflicting heavy casualties on NATO and Afghan government forces but also on civilians.
So far this month, seven coalition members have died in Afghanistan, bringing the year’s toll to 139.
