A suicide bomb attack has killed at least nine people in north-western Pakistan.

The blast went off at the entrance to an anti-Taliban commander's compound in Kurram, part of the tribal regions which border Afghanistan.

According reports the compound is used by a local militia and also contains residential units.

Pakistan's military has been carrying out operations against militant groups in the tribal regions for months.

Tribal police officials have told the media that three children were among the dead and at least 15 people were injured.

The compound belongs to a militant commander, Mullah Nabi, who split from the Pakistani Taliban.
