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.

General António Guterres on Friday described the humanitarian aid cuts by the United States and other countries in Europe as "a crime.”Guterres was on a four-day visit to Bangladesh where he is assessing the plight of more than 1 million Rohingya refugees whose future remained uncertain over possible aid cuts soon.

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