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

The United Nations will do all it can to help prevent food rations being cut for Rohingya refugees in camps in Bangladesh, U.N. Secretary-General Antonio Guterres said on Friday during a visit to the world’s largest refugee settlement.

UN Secretary-General António Guterres, during his visit to the Rohingya refugee camps in southern Bangladesh, vowed to do everything in his power to prevent further hardship as drastic aid cuts threaten food supplies and other critical relief efforts.

U.N. Secretary-General António Guterres arrived in Bangladesh on Thursday on a four-day visit to review the situation of more than 1 million Rohingya refugees amid the fear of aid cuts that could seriously affect them.

According to diplomatic sources, the UN has been seeking to send humanitarian aid to Rakhine through Bangladesh amid a fear of famine-like situation there as was reported by the UNDP in November last year.

Rohingya refugees in crammed Bangladeshi camps say they are worried about a U.S. decision to cut food rations by half beginning next month, while a refugee official says the reduction will impact the nutrition of more than 1 million refugees and create social and mental pressure.

The leader of the United Nations and the chief of Bangladesh’s interim government were joined by about 100,000 Rohingya refugees for iftar – the meal to break the fast at sundown during Ramadan – at the Ukhia camp in Cox’s Bazar on Friday.
