From inside a small cell in the Muwaqqar prison in the desert south of Jordan’s capital, Amman, a Jordanian preacher of Palestinian origin named Omar Mahmoud Othman, aka Abu Qatada, whom British authorities deported to Jordan, is organizing the jihadist Salafist movement in the country. Abu Qatada has taken the banner from the spiritual reference of the jihadists in Jordan and the world, Issam al-Barqawi, aka Abu Muhammad al-Maqdisi. The latter has been imprisoned by Jordanian authorities for several years on terrorism charges.
