Middle East leaders and their Western allies have been warning that Islamic State could exploit the fall of the Assad regime to stage a comeback in Syria and neighbouring Iraq. Islamic State (IS) has been attempting just that, according to more than 20 sources, including security and political officials from Syria, Iraq, the U.S. and Europe, as well as diplomats in the region. The group has started reactivating fighters in both countries, identifying targets, distributing weapons and stepping up recruitment and propaganda efforts, the sources said.
