COX'S BAZAR, BANGLADESH - Rohingya refugee ⁠Rahila Begum spent two days adrift in the Andaman Sea this month, clinging to a wooden shard after her overcrowded boat capsized, one of the few survivors of a disaster that left 250 missing and feared dead.She was among the thousands of Rohingya Muslims who brave hunger and accidents on rickety boats each year to flee desperate conditions in camps in southeastern Bangladesh for countries such as Indonesia and Malaysia.Hundreds die en route from hunger or accidents at sea, but the numbers keep growing as shrinking food rations ​caused by dwindling international aid push yet more to make the dangerous crossing.
