CEDAR RAPIDS, Iowa — Hillary Rodham Clinton is calling for a “concerted global effort” to assist the hundreds of thousands of refugees from the Middle East, Africa and Asia seeking refuge in Europe.

In an interview with The Associated Press, the front-runner for the Democratic presidential nomination said Monday that “everyone should be asked to do more” to help the migrants, many of whom are fleeing the civil war in Syria and from areas in that country and in Iraq under the control of Islamic State militants.

“I think we need to have a broad-based global response,” Clinton said before spending Labor Day campaigning in eastern Iowa and parts of Illinois. “The United States certainly should be at the table, but so should everybody else.”
