A Syrian man who had fled the war in his homeland stands outside shops run by Syrians in a low-income neighborhood of Ankara, Turkey, September 29, 2015. Nearly five years after the conflict in Syria began, Turkey has shouldered the brunt of the humanitarian burden, sheltering at least 2.3 million Syrians, the largest refugee population in the world. But tensions are simmering between Turk and Syrians as it struggles to integrate a population that does not speak the language and is largely prevented from working. Turkey's refugee camps can house only a fraction of the refugees, who prefer to take their chances in Turkish cities, where they look for low-paid employment or resort to begging. Initial optimism on the part of both refugees and their hosts has given way to resentment and mistrust, helping fuel a tide of migrants fleeing countries that are poor or at war and hoping to reach - legally or illegally - the wealthy EU.

Myanmar's decision to revoke temporary identification cards for minorities is raising tensions among its 1.1 million Rohingya Muslims, who have effectively been disenfranchised just days after parliament approved a law affirming their right to vote in a referendum. Last week, the government of the Buddhist-majority nation announced that the temporary identification, known as white cards, would be revoked on May 31.
