Pakistani activists from Muttahida Majlis-e-Amal and Muttahida Qaumi Movement (MQM) chant anti-U.S. slogans during a protest in Islamabad January 15, 2006. Thousands of people rallied across Pakistan on Sunday to protest against a U.S. airstrike in a tribal region that killed at least 18 people but missed its apparent target, al Qaeda's number two, Ayman al Zawahri. Pakistani officials say there is no evidence Osama bin Laden's deputy was there when aircraft struck Damadola village in Bajaur tribal region, near the Afghan border, early on Friday.
