An Afghan man wearing the uniform of the country’s security forces turned his weapon on Nato troops in eastern Afghanistan, killing a member of the international coalition.
The Taliban claimed responsibility for the killing, which took place in eastern Paktia province. It was the second so-called insider attack in less than a week by a member of the Afghan forces against their international allies.
Nato said the attacker was killed but provided no other details. The alliance said the international forces were investigating the shooting, which they have not yet classified as an insider attack.
Taliban spokesman Zabihullah Mujahid sent a text message to the media claiming responsibility for the attack.
The shooting took place on an Afghan base in the Gerda Sarai district, a spokesman for the governor of eastern Paktia, Rohullah Samon, said.
Attiqullah Khan, district chief of Gerda Sarai, confirmed the attack but had no more details.
Three American soldiers were killed by an Afghan soldier on September 21 in Paktia.
Killings by uniformed Afghans of foreign soldiers and civilians rose dramatically last year, eroding confidence between the sides at a crucial turning point in the conflict. So-called insider attacks killed 62 personnel in 47 incidents last year, compared with 35 killed in 21 attacks a year earlier, according to Nato.
So far in 2013, 12 foreign soldiers have been killed in eight such attacks, including Thursday’s, according to an Associated Press count.
In some cases, militants have donned Afghan army or police uniforms to attack foreign troops, but a number have been carried out by members of Afghan security forces against their own comrades.
The attacks come as Nato and Afghan forces are working more closely, with foreign troops handing over security to the Afghans and continuing to train them prior to an almost total withdrawal by the end of 2014.
