ISLAMABAD, July 16 (Xinhua) -- At least three policemen were injured as a remote-controlled bomb hit a police vehicle Friday morning in Hangu area of the Orakzai tribal agency in northwest Pakistan, local media reported.
According to the report, the police vehicle was destroyed in the explosion. No group has claimed responsibility for the attack.
The attack is believed to be an act taken by militants in retaliation to the military operations stepped up by the Pakistani army against them in the area.
Over the last week or so, the reinforced military operations launched by the Pakistani security forces in Orakzai, a stronghold of militants in Pakistan, have delivered a heavy blow to the militants hiding in the area, killing almost an average of a dozen of militants on a daily basis.
