A gunfight broke out between Afghan and foreign soldiers on the outskirts of the capital Kabul on Saturday, leaving at least one Afghan serviceman dead and a number of other soldiers injured on Saturday, according to Afghan and NATO officials.
So-called "insider attacks" are severely straining ties between the NATO-led alliance and the Kabul authorities and further undermine waning support for the war in the West. They have become one of the Taliban insurgents' most effective weapons against the coalition.
"There was an argument between an Afghan and foreign soldier inside a military base... where they opened fire on each other. An investigation is ongoing," defence ministry spokesman Dawlat Waziri said.
The soldier killed was Afghan, a spokesman for the NATO-led force said. A number of others were reported to have been injured.
