FILE - In this Wednesday, July 27, 2011 file photo provided by IntelCenter, an American private terrorist threat analysis company, purports to show Al-Qaida's new leader Ayman al-Zawahiri in a still image from a web posting by al-Qaida's media arm, as-Sahab. The leader of al-Qaida has urged Muslims to kidnap Westerners to exchange for imprisoned jihadists. Ayman Al-Zawahri also urged support for Syria's uprising and called for the implementation of Islamic Shariah law in Egypt. In an undated two-hour videotape posted this week on militant forums, the Egyptian-born jihadist said that abducting nationals of "countries waging wars on Muslims" is the only way to free "our captives, and Sheik Omar Abdel-Rahman," the Egyptian cleric serving a life sentence in U.S. prisons for his masterminding of 1993 bombings in New York City.
