Painfully thin children were being measured for height at refugee camps in Cox's Bazar, as women are being shown how to prepare meals for their malnourished children.
"Nearly 90 percent of them (Rohingya refugees) has informed us that they are living on one meal per day," UNICEF's Sakil Faizullah said.
"By this malnutrition program, we're now treating 3,400 severely acute malnourished children," Action Against Hunger's Muhammad Mehedi said.
"And also we have mental health components, so by this mental health component we're going to cover 30,000 persons under these mental health services.
And still now we provide service to 8,400 traumatised children and mothers."
More than 500,000 Rohingya Muslims are now living in camps in Bangladesh's Cox's Bazar district.
The refugees have come by land, river and sea, trekking for days in monsoon weather to find sanctuary in Bangladesh after Rohingya Muslim insurgents attacked security posts in Myanmar, prompting its military to unleash a sweeping offensive across the north of Rakhine State in what the United Nations branded a textbook example of "ethnic cleansing"
