Migrants wait on the rocks on the shoreline under the surveillance of policemen, on September 30, 2015 at the French-Italian border in Ventimiglia. The camp of around 50 people at Ventimiglia -- the town which became a flashpoint at the start of Europe's migrant crisis earlier this year -- was cleared because its occupants were using electricity and water without paying for it, a police spokesman said. Some 30 migrants and 20 Italian activists, who had been warned ahead of the evacuation, moved to the coastal rocks before dawn to be well clear once police arrived at nearly 6:30am, Italian deputy police chief Giuseppe Maggese said. .

Retired General John Allen, the special presidential envoy for the global coalition against Islamic State, speaks during a House Foreign Affairs Committee hearing in Washington, D.C., U.S., on Thursday, March 26, 2015. The U.S. and allies began airstrikes on the Iraqi city of Tikrit, supporting Iranian-backed Shiite militias seeking to expel Islamic State fighters from the area. Asked whether Iran could end up controlling Iraq, Allen said, "I don't think that's going to be the case. In the end, Iraq is an Arab country." Iranians, he said, "are a different people."

FREILASSING, GERMANY - SEPTEMBER 14: A cordon is set up in front of migrants in police custody as they wait to be brought to emergency accomodations on September 14, 2015 at the railway station in Freilassing, Germany. German authorities announced they are temporarily reinstating border controls along Germany's border to Austria in order to stem the recent massive influx of migrants and uphold the Dublin agreement. Tens of thousands of migrants arrived in Germany over the last few weeks and the country is struggling to find adequate accommodation for them all. By enforcing the Dublin agreement, which requires migrants applying for asylum to register in the first EU country they enter, German authorities are hoping for a broader distribution of arriving migrants across EU member states.
