U.S. President George W. Bush waves to the press on the South Lawn of the White House in Washington, March 18, 2004. The President said there was no new information on reports that Pakistani troops may have cornered Osama bin Laden's number two Ayman al-Zawahri on the Afghanistan/Pakistan frontier. Pakistani troops may have cornered Osama bin Laden's number two during a major battle on the frontier on Thursday, top officials said. A senior government official in Islamabad told Reuters that Ayman al-Zawahri, bin Laden's right-hand man in the Islamist network, may be surrounded. Another official said the trapped leader was not bin Laden, the Western world's most wanted man. REUTERS/William Philpott WP/JDP
