Raqqa (Syria) - A civil council expected to rule Raqqa once Islamic State is dislodged from the Syrian city pardoned 83 of the jihadist group's low-ranking militants on Saturday, a goodwill gesture designed to promote stability. The U.S.-backed Syrian Democratic Forces (SDF) have gained significant ground in the battle for Raqqa, the operational base for Islamic State over the past three years and a symbol of its self-proclaimed caliphate. Senior SDF figures predict Raqqa could fall within months. That would be a severe blow to Islamic State, which has plotted shooting and bomb attacks around the world from Raqqa, a city of about 300,000 before the militants seized it. The 83 Islamic State prisoners were transported to the headquarters of the Raqqa City Council in the village of Ain Issa, north of Raqqa, in an amnesty coinciding with the Eid al-Fitr holiday marking the end of the Muslim fasting month of Ramadan.
