WASHINGTON (Reuters) - President Barack Obama in a phone call with German Chancellor Angela Merkel on Wednesday voiced appreciation for her leadership in dealing with the migration crisis in Europe, the White House said.

Obama particularly cited Merkel's recent decision to ease the burden on other countries by providing haven to Syrian refugees, the White House statement added.

The surge in migrants seeking refuge from conflict or poverty in the Middle East, Africa and Asia has confronted Europe with its worst refugee crisis since World War Two.
