A Pakistani government official says a bomb has exploded at a market in a tribal region close to the Afghan border, targeting a group of anti-Taliban militiamen. One fighter was killed in the blast. Tariq Khan, a local administrator in Salarzai town of the Bajur tribal area, says Sunday's bombing also wounded two militiamen and a bystander. Khan says the attackers detonated the bomb at the town market by remote control, according to a report of the Associated Press.
