The economies of Arab countries rocked by the uprisings that swept the region two years ago, remain sluggish because of unfinished political transitions, a top IMF official told AFP. Others are suffering from the financial and social burdens imposed on them by a huge influx of refugees from the civil war in Syria, International Monetary Fund director for the Middle East and Central Asia Masood Ahmed said in an interview. "The situation in Arab Spring nations has become more challenging over the past year," Ahmed said. The economies of Tunisia and Egypt have seen weak growth since the uprisings that ousted their longtime leaders in 2011.
