In this December 3, 2016, file photo, Rohingya women and children wait in a queue to collect water at the Leda camp, an unregistered camp for Rohingya in Teknaf, near Cox's Bazar, a southern coastal district about, 296 kilometers (183 miles) south of Dhaka, Bangladesh. Newly revealed video of Myanmar police beating Rohingya Muslims in northern Rakhine state has weakened months of government claims that its forces have not committed abuses in the region since a deadly insurgent attack in October. The footage has made it more difficult for the government to say at least some abuses are not happening and sown doubts into its dismissals of more grievous allegations. (Photo by AP Photo)
