KABUL, Afghanistan – An American member of the service was killed and another injured when an Afghan commander opened fire on them on Saturday in Kabul, Afghan and US officials said.
It was the second such attack in less than two weeks.
On October 22, an Afghan commander opened fire on members of the US NATO coalition in the western province of Herat, killing one and injuring two.
"Initial reports indicate that the attacker was a member of Afghanistan's national defense and security forces," said Debra Richardson, a NATO spokesman in the capital of Kabul.
"The attacker was immediately killed by other Afghan forces."
The NATO statement did not release the identity or ranks of the members of the service or the position of the attack.
However, United States officials suggested it had happened to a hub of US special forces in Kabul, which is used as a career base for missions around the capital and neighboring provinces.
So-called attacks of confiscation have long been a problem for coalition forces in Afghanistan. At their peak in 2012, The 61 coalition soldiers were killed by such attacks.
The latest assault came as the US army retreated to a more cautious position after a widespread reputation for killing the powerful Kandahar province's chief of police, which created distrust of Afghan allies.
On October 18, the captain, General Abdul Raziq, was shot by a teenage persecution of the Taliban as he walked from a meeting with the top governor of America and NATO, Gen. Austin S. Miller.
General Miller, who stood afar off, survived a second round that was fired in the direction of other officials.
This led to tensions with Afghan forces that threw a cloud over the relationship. Afghan and American forces collided as the US escort left the union, with the United States forces firing an Afghan guard dead.
The US military has struggled to curb misinformation, and senior Afghan officials have tried to abolish reputation.
Anxiety culminated after an Afghan commander opened fire against coalition forces on October 22 in the west of the country, following what the Afghan officials had had was an oral conflict over the assassination of General Razi.
