MAZAR-I-SHARIF: A Nato helicopter opened fire on a car in northern Afghanistan Thursday, killing a police officer and a local politician's brother, the governor of Faryab province told AFP.

Abdul Haq Shafaq said he was driving on the same road in his official convoy when the car came under attack from a Nato helicopter, around five kilometres outside the provincial capital, Maymana.

“We were on the same road. Five cars were coming from the opposite direction. All of a sudden we saw a Nato helicopter firing at one of those cars. A police officer and the brother of a lawmaker were killed,” Shafaq said.
