A bomb blast following a political rally has killed at least six people in northwest Pakistan.

Monday's attack took place in the town of Nowshera in Khyber-Pakhtunkhwa province.

Authorities say the bomb, which was planted on a motorcycle, exploded as top officials from the province's ruling Awami National party left a political rally.

The attack wounded at least 14 people.

The chief minister of Khyber-Pakhtunkhwa, Ameer Haider Khan Hoti, was at the meeting, but not hurt in the attack.
