Two US service members died today when another Afghan policeman turned his weapon on American allies in Afghanistan.
Today’s killing in the country’s west is the sixth such incident in two weeks.
The shooting happened in the far western province of Farah and the attacker was a member of the Afghan local police, a village defence force being trained by international forces, including US special forces.
Two American service members died before the Afghan attacker was shot and killed.
Attacks by Afghan allies on international troops have accelerated this year, killing at least 36 foreign troops and raising questions about the strategy to train Afghans to take over security in 2014.
