The Syria move is seen as an attempt by the Arab state to reduce the flow of more than 30,000 Iraqi refugees every month. But it remains unclear how it will affect Iraqis seeking refugee status.

Earlier today, the head of the UN refugee agency praised Syria and Jordan for taking in fleeing Iraqis, and urged the international community to show its solidarity by providing more support.

Antonio Guterres, the United Nations High Commissioner for Refugees, also highlighted the need to separate regional politics -- especially regarding Syria -- from the humanitarian problem at hand.

Jordan and Syria host the largest percentage of the more than 2 million Iraqis who have fled abroad.

This week, the United States said it would increase its support by $30 million to countries hosting Iraqi refugees.
