Afghan officials say U.S.-led coalition soldiers accidentally killed five Afghan police officers in the troubled south.
A deputy police chief in Helmand province says American troops mistakenly thought Afghan officers manning a checkpoint were militants late Thursday. He said U.S. troops opened fire in the Gereshk district of southern Helmand province, killing five.
But two U.S. coalition spokesmen have said there is no indication that U.S. soldiers were involved in the incident. A spokesman for a separate NATO force in Afghanistan says its troops were not involved either.
Also Friday, authorities in eastern Afghanistan say a suicide bomber struck near an army patrol in Konar province, wounding two soldiers and one civilian.
