Three more soldiers have been killed in a second attack against NATO troops in Afghanistan within a week.
This latest incident involves the shooting of three foreign troops by an Afghan civilian worker.
It follows the deaths of three US marines who were invited to dinner then fired at by an Afghan police commander and local officers.
Both shootings took place in Helmand province.
“Let me clearly say that those two incidents clearly don’t reflect the overall situation here in Afghanistan. We have almost 500,000 police and soldiers working together, side by side, in order to fight for a better future for this country,” said NATO spokesman Brigadier-General Gunter Katz
The loss of NATO soldiers is escalating – particularly from green on blue shootings, where Afghan security turn on foreign troops. More than 30 coalition soldiers have been killed in these attacks since January.
