A bomb exploded Wednesday at the office of a lawmaker in central Pakistan, killing at least seven people and wounding several others.
The blast happened in Taunsa, a town in Punjab province, at an office used by Amjad Khosa of Pakistan's ruling Pakistan Muslim League. Khosa was not at the site at the time of the attack.
Police said they were investigating the blast as a suicide bombing.
There was no immediate claim of responsibility, but the Pakistani Taliban has carried out numerous bombings against officials in recent years.
Tens of thousands of Pakistanis have died during the Taliban's bloody insurgency to impose its brand of Islam and avenge military attacks against its bases in the northwestern tribal areas along Pakistan's border with Afghanistan.
The Pakistani military launched an offensive in June 2014 in the tribal areas and other parts of Pakistan that authorities say has drastically reduced violence.
