Helmand provincial police chief General Mohammad Hussain Andiwal told AFP that the NATO soldiers had opened fire on the policemen at around midnight, killing one and wounding another.
“I don’t know why they did this because the policemen were in uniform and they were moving near the police vehicle,” he said.
The British military in Lashkar Gah confirmed the incident and said a British soldier was also wounded.
