Rohingya and Bangladeshi migrants who arrived in Indonesia by boat receive medical assistance at an aid station in Kuala Langsa in Indonesia's Aceh Province May 15, 2015. Nearly 800 "boat people" were brought ashore in Indonesia on Friday, but other vessels crammed with migrants were sent back to sea despite a UN call to rescue thousands adrift in Southeast Asian waters with dwindling supplies of food and water.
