A Pakistani police officer says a bomb blast has killed a local leader in an anti-Taliban political party in the northwestern Swat valley.

Abdullah Khan says the bomb planted near Mukarram Shah's car exploded Sunday in the village of Banjot. He says it appear to have been set off by remote control.

Shah comes from the secular Awami National Party, which supported military operations against militants in the region.

The ANP is among three secular-leaning political parties that the Pakistani Taliban have threatened to attack during campaigns for parliamentary elections to be held on May 11.

The three dominated Pakistan's last government, dissolved in preparation for the elections. The ANP also headed the government of Khyber Pakhtunkhwa province in which Swat is located.
