“There is an urgent need for shelter materials,” the spokesperson for the Office of the UN High Commissioner for Refugees (UNHCR), Andrej Mahecic, told journalists in Geneva.

“Food rations, drinking water and latrines are some of the other needs identified so far in the cyclone-affected areas,” Mahecic said, adding that more needs are likely to be identified as governments in Bangladesh and Myanmar complete their ongoing assessments of the damage.

The Rohingya community displaced in Myanmar and living in settlements in Bangladesh has been particularly hard hit. In Bangladesh, there are more than 33,000 Rohingya refugees registered in the official camps of Kutupalong and Nayapara. Outside the camps, more than 300,000 undocumented Rohingya are living in makeshift sites and local villages in the south-eastern part of the country.

In Myanmar, some 130,500 internally displaced people have been living in central Rakhine since 3013, when inter-communal violence forced them to flee, according to UNHCR.

The International Organization for Migration (IOM) on Friday launched an appeal for $3.7 million to help the Rohingya in Bangladesh. The funds aim to help up to 80,000 people between now and the end of the year, and “will target health, water, sanitation, shelter and protection.”

The cyclone, which pounded Bangladesh with 117 km/hour winds and heavy train, tore through the settlement houses which offered little resistance to the storm’s strength.

“The storm destroyed35 per cent of shelters and left as many as 80 per cent damaged,” IOM said. “Food and fuel supplies were destroyed, electricity lines were cut, and health and sanitation infrastructure was also badly damaged.”

Some 1.3 million children are estimated to be in urgent need of aid as a result of the storm.

The Director of Emergency Programmes at the UN Children’s Fund (UNICEF), Manuel Fontaine, warned that children from the Rohingya community, who were already displaced and living in precarious conditions before the Cyclone, is now “hit by double humanitarian crisis.”
