The attack was the latest in a series of apparent air or missile strikes on the Pakistan side of the border with Afghanistan, unexplained by authorities but widely suspected to have targeted terror suspects or Islamic militants.
Last Saturday, an attack on a cleric's home in North Waziristan, 125 miles southwest of Bajur, killed eight people. Local tribesmen claimed U.S. helicopters launched the attack and took away five tribesmen. Pakistan's government protested to the U.S. military in Afghanistan. The U.S. military denied it had bombed the area.
Last month, a senior al-Qaida suspect from Egypt, Hamza Rabia, was killed in North Waziristan. Pakistan denied residents' claims that he died in a U.S. missile strike.
In early 2004 during a major Pakistani counterterrorism operation in neighboring South Waziristan, Pakistani officials said on condition of anonymity that al-Zawahri was believed to be hiding in the area, but the reports were never substantiated.
Pakistan has tens of thousands of forces deployed along the Afghan border to hunt al-Qaida and Taliban militants and maintains a sensitive alliance with the United States in its war on terror, which is opposed by many in this Islamic nation of 150 million people. Pakistan says it does not allow Afghan or the 20,000 U.S. forces in Afghanistan to operate on its soil.
"Our people say Americans did it," Rashid said. "If it is true, then Pakistan should lodge a strong protest with the U.S. government for killing innocent people."
