Since the revolution in Tunisia, where the Arab Spring began, there is an increasing concern that the extreme views of the conservative Salafists are spreading. The group is led by Seif Allah Benahssine, also known as Abu Iyadh, who is now wanted for allegedly encouraging the attack of the American embassy in the capital Tunis. But reports said Abu Iyadh managed to slip from police cordon under the cover of his supporters, leaving government authorities looking helpless. Al Jazeera's Nazanine Moshiri reports from Tunis.
