ISLAMABAD: A bomb exploded outside the district police headquarters in northwest Pakistan’s Lakki Marwat town, killing one passer-by and wounding two others, police said.

Police official Rafique Khan said the explosion on Friday happened in Lakki Marwat, a town about 110 miles south of Peshawar.

Khan said the wounded were local residents, but the dead passer-by had yet to be identified.
