Thousands of Rohingya Muslims and Bangladeshis abandoned at sea had nowhere to turn on Thursday as Malaysia turned away two boats crammed with more than 800 migrants, saying it could not afford to keep being nice. Indonesia and Thailand also appeared unwilling to provide refuge to men, women and children, despite appeals by the UN High Commissioner for Refugees, international aid agencies and rights activists, who warned lives were at risk. Fearing arrests, captains tied to trafficking networks have abandoned ships in the busy Malacca Strait and surrounding waters, leaving behind their human cargo, with little food or water.
