Officials in northwest Pakistan say a bomb blast has ripped through a restaurant at a market, killing eight people and wounding 10 other people. 
Authorities say the attack happened Saturday at a bazaar in the Salarzai area of the restive Bajur tribal region near the Afghan border. 
Local officials say two pro-government elders were among dead. 
Taliban militants have targeted members of the Salarzai tribe in the past because the tribe has formed a militia to drive the militants out of the region. 
No one has claimed responsibility for the attack.
