New jihadi anti-American incitement features an animated clip of a sword beheading U.S. President Barack Obama. Other candidates for beheading in the clip are U.S. Secretary of Defense Robert Gates, U.S. General David Petraeus and Pope Benedict. The website’s message, translated by Middle East Media Research Institute (MEMRI), was posted Monday by someone calling himself “Sama Baghdad,” who described himself as "a student at the Al-Fallujah Islamic University,” meaning a member on the website's Islamic jurisprudence forum. The message was headed "Retaliation and Revenge for the Killing of the Two Sheikhs – Part One," and a link to the animated clip was presented as the first of a series and dedicated to “Crusader infidels.” The author explained that the clip urges the Muslims to avenge the killing of the two martyrs – 'Omar Al-Baghdadi, Emir of the Islamic State of Iraq (ISI) and its "war minister" Abu Hamza Al-Muhajir, who were killed in a joint U.S.-Iraqi strike in April. In a response to members of the website’s forums, “Baghdad” write that the “images will gladden your heart.”
