Barack Obama orders US to admit 10,000 Syrian refugees

President Barack Obama has asked for at least 10,000 Syrian refugees to be admitted to the United States next year, amid criticism his government has done too little to help.

Spokesman Josh Earnest yesterday said Obama had asked staff to "scale up" the number of refugee admissions, which are likely to total around 1,800 in the fiscal year ending September 30.

"He has informed his team that he would like them to make preparations to accept at least 10,000 Syrian refugees in the next fiscal year," said Earnest.

Around the world, voters shocked by images of drowning refugees have put pressure on their governments to act.

More than 62,000 Americans have signed a petition calling on Obama's administration to resettle at least 65,000 Syrians by 2016.

Earnest defended the administration's response, saying the US could not realistically provide sanctuary to the four million Syrians who have fled a brutal civil war.

"We know the scale of this problem, and it's significant, there are millions of people who have been driven from their homes because of this violence."

"What we can do is make sure we are doing anything we can to try to provide for their basic needs. That is why the United States has continued to be the largest donor of humanitarian assistance."

US humanitarian funding for the crisis has totaled around USD 4 billion.

The United States currently accepts around 70,000 refugees a year from all conflicts around the world and has been particularly slow to accept Syrians.

Federal Bureau of Investigation director James Comey was asked Thursday about the risk of Islamic State group extremists infiltrating the Syrian refugees coming into the United States.

"That's a threat we have to worry about," he said. "We have to make sure we understand who is coming in... Because there is a risk here."

Refugees from the country must undergo strict security checks designed to weed out extremists, even after being registered by the United Nations.

"The process to bring refugees here is careful and deliberate," a senior State Department official said Wednesday.
