A Syrian refugee carries his son through a rainstorm towards the Greek-Macedonian border

A Syrian refugee kisses his son as he walks through a rainstorm towards Greece’s border with Macedonia, near the Greek village of Idomeni, September 10, 2015. Most of the people flooding into Europe are refes fleeing violence and persecution in their home countries who have a legal right to seek asylum, the United Nations said on Tuesday.
