In this Nov. 4, 2017, photo, Rohingya Muslim Nabi Hussain, 13, poses for a portrait with the yellow plastic drum he used as a flotation device while crossing the Naf river in Shar Porir Dwip, south Cox's Bazar, Bangladesh. The Naf river is a natural border between Myanmar and Bangladesh. Nabi couldn't swim, and had never even seen the sea before fleeing his village in Myanmar. But he clung to the empty drum and struggled across the water with it for about 2.5 miles, all the way to Bangladesh. (AP Photo/Bernat Armangue)
