A suicide bomber attacked police in Herat province west of Afghanistan on Friday, killing at least one policeman and wounding two others, police said, Xinhua reported.
"A terrorist riding an explosive-laden car blew it up next to the convoy of police in Gazara district at 8 a.m., leaving one police constable dead and two others dead," deputy to provincial police chief Dilawar Shah Dilawar told Xinhua.
Close to the incident was NATO-led forces base but it caused no damage to the alliance, Dilawar further said.
The suicide bomber was also killed in the blast, he said.
He also blamed the "enemies of peace," a term used against Taliban militants but the outfit has yet to make comment.
Taliban militants fighting Afghan and NATO-led troops have vowed to speed up activities this year in Afghanistan.
More than 80 people, including over 30 NATO soldiers, have been killed in Taliban-linked activities, mostly in roadside bombings and suicide attacks, so far in July in the militancy-plagued Afghanistan.
