UNITED NEWS INTERNATIONAL (UNI) —The first monsoon rains have crippled Rohingya refugee camps in Bangladesh, destroying shelters and prompting floods and 21 landslides Sunday, June 10.

CNN reported on Monday that the first casualty was a three-year-old boy who died when a mud wall in a shelter caved in on him and his mother.

The forecast for the coming days calls for more heavy rain, sparking concerns that a humanitarian disaster is around the corner.

UN refugee agency spokesperson Caroline Gluck told Agence France-Presse the monsoon season would be harrowing.

Gluck said the rainy season “is going to be a big test for everybody involved in the humanitarian response in support of the government of Bangladesh.”

Officials say an estimated 300 family shelters have been damaged.

Roughly 29,000 refugees out of the 200,000 at risk have been relocated to new safe areas.
