MIRANSHAH, PAKISTAN - A suicide bomber killed at least ten people, including an election candidate, and wounded 13 others in Pakistan's tribal region of North Waziristan on Monday, tribal police said.

The attacker rammed a car laden with explosives into the candidate's convoy as it headed to a rally ahead of elections due in a week's time, police officials said on condition of anonymity.

"Ten people were killed, including election candidate Nisar Ali and an administration official, while 13 others were wounded in the attack on their convoy," one official said.
