At least four policemen were killed and one injured Tuesday by a roadside bomb in south-eastern Afghanistan, an official said, dpa reported.
"A vehicle of policemen from the Public Protection Unit struck a roadside bomb this morning in Andar district. Three police were killed on the spot and two others were wounded," said Mohammad Ali Ahmadi, deputy governor of Ghazni province.
"One of the injured died in the hospital," he said.
He blamed the "enemies of the country" for the attack, a term usually used by Afghan officials to refer Taliban insurgents.
Nobody had yet claimed responsibility for the attack.
