The U.N.'s special envoy on human rights in Myanmar has said that conditions in camps for members of the Muslim Rohingya minority, forced from their homes four years ago by communal violence, remain poor with overcrowding, the deterioration of temporary housing, and a lack of proper sanitation facilities.

Speaking at the end of a 12-day visit, Special Rapporteur Yanghee Lee said ending institutionalized discrimination against the Muslim communities in western Rakhine State must be an urgent priority, and restrictions on them cannot be justified on grounds of security or ensuring stability. There are more than 100,000 Rohingya living in the camps.

Discrimination against the Rohingya is widespread and the government refuses to recognize most as citizens, treating even long-term residents as illegal immigrants.
