Teenager suicide bomber kills 18 in Pakistan's bus

A teen-aged suicide bomber killed at least 18 people and wounded 33 others on board a bus Wednesday in northwest Pakistan, officials said.

The teenager detonated explosives on the bus as it was about to drive off at the Tirah Bazar market in Kohat, according to city police chief Dilawar Bangish. Kohat is in the Khyber Pakhtunkhwa province, formerly known as the North West Frontier Province, according to CNN.

According to police the target was a tribal chief opposed to Pakistan's Taliban whose stronghold is in the northwest of the country. A campaign of suicide bombings continues despite military offensives by Pakistan's US-backed government, euronews reports.
