Europe must be prepared for an influx of Islamic State militants if Iraqi forces retake control of Mosul, the EU’s security commissioner has warned. Thousands of Europeans have gone to Iraq and Syria over the past two years to fight with Isis, but the Islamist extremists have suffered a string of defeats in recent months in both countries. Those defeats have prompted some of its fighters to begin returning to the continent, but about 2,500 European fighters remain in the conflict zones, King told the German newspaper Die Welt.
