A summit hosted by U.S. President Barack Obama garnered pledges from dozens of countries to resettle or allow the lawful admission of some 360,000 refugees, doubling the number of slots that were available last year, the U.S. envoy to the United Nations said.

But Ambassador Samantha Power said that was “still only a fraction” of what was needed because the U.N. refugee agency, UNHCR, has assessed that some 1.2 million refugees need to be resettled.

Countries could only attend Obama’s summit at the annual U.N. gathering of world leaders if they made a pledge.
