The Republican-led House Committee on Homeland Security is challenging an Obama administration plan to admit Syrian refugees to the United States, saying it could allow potential terrorists to sneak into the country.
Turkey opened its biggest refugee camp on Sunday to house 35,000 people fleeing fighting between Kurdish forces and Islamist militants in Syria's Kobani, national disaster management agency AFAD said.
Iran said it had agreed to extend temporary visas for 450,000 Afghan refugees for six months, lifting a threat to send them back home to a country facing attacks by resurgent militants.
The United States pledged an additional $135 million in aid for the victims of the Syrian war on Saturday, much of it to help the United Nations with a funding shortfall it had warned could force it to scale back food distribution.
