Save the Children, an international non-government organization, has expressed its concern as the week long heavy monsoon rains in Cox's Bazar have led to landslides and waterlogging, affecting more than half a million children in the Rohingya refugee camps and the host community.
In a press release on Thursday, the organization said further bad weather could result in a major humanitarian crisis leading to more deaths, injury and mass displacement along with the potential spread of water-borne diseases.
Save the Children's Deputy Country Director in Bangladesh Dr Ishtiaq Mannan said: "We are deeply concerned about the safety and well-being of half a million children living in the Rohingya refugee camps in Cox's Bazar and in the host communities.
"Lingering monsoons and frequent flashfloods could increasingly put lives at risk. At least three Bangladeshi children have already died when a rain-soaked hill above their home collapsed. It is vital that we protect vulnerable communities from the effects of extreme weather, which is only likely to get worse with climate change," he said.
More than one million Rohingya refugees living in flimsy bamboo shelters in Cox's Bazar are also in need of assistance following days of heavy rain that has turned roads into mud, the press release said.
Many Rohingya refugees have been displaced by the rains, because their shelters were either partially or completely destroyed, it said.
Rohingya Response Team Leader in Cox's Bazar David Skinner said: "Our teams are working tirelessly in the camps and closely monitoring the situation, rushing to repair damaged structures so that we can continue to provide vital services for Rohingya refugees in Cox's Bazar.
"At least 200 of the Save the Children's facilities have been damaged including a dozen of our learning centres and child-friendly spaces. We must get them up and running as soon as possible because these are often the only places Rohingya refugee children can learn and play in a safe and supportive environment," he added.
