MIRANSHAH (AFP/Reuters) Taliban militants strapped bombs to two men they accused of spying for the United States, blowing them up at a public execution, security officials said Friday. The Taliban frequently kidnap and kill tribesmen in the lawless tribal belt shadowing the Afghan border, but traditionally slit their throats or shoot them. Locals said it was the first such killing with bombs. The incident took place in the Degan area of North Waziristan. Five masked militants paraded the handcuffed men before dozens of people and accused them of passing information to the United States on targets for its CIA-operated pilotless drone aircraft. They strapped explosives around their bodies and then blew them up, an intelligence official in the region told Reuters by telephone. The Taliban threatened anyone spying for the United States with the same fate and called on locals to witness the public execution late Thursday in an announcement made through a local mosque. The Taliban recently captured the tribesmen and accused them of passing on information to the Americans, which led to US missile strikes around Inzarkas, the intelligence official said. A barrage of US missile attacks in the area killed up to 24 militants this month, only days after US officials arrested Pakistani-American Faisal Shahzad on charges of trying to plant a car bomb in New Yorks Times Square.
