U.N. Secretary-General Antonio Guterres is visiting Rohingya refugees in Bangladesh as their food rations face drastic cuts amid a funding shortfall, threatening already dire living conditions in the world’s largest refugee settlement.

U.N. Secretary-General António Guterres has described humanitarian aid cuts by the United States and other countries as “a crime.”

Antonio Guterres’ visit comes after WFP says it may have to halve food vouchers for Rohingya starting next month.
