Some 90,000 Rohingya Muslims have fled to Bangladesh since violence broke out in Myanmar in August, with aid officials warning relief camps are reaching full capacity.

The continued clashes have killed at least 400 people, the Express Tribune reported.

The total number of Rohingya who have fled Myanmar since October have reached 150,000, UN aid workers said.

“We are trying to build houses here, but there isn’t enough space,” said Mohammed Hussein, who has fled Myanmar days ago.

“No non-government organizations came here. We have no food. Some women gave birth on the roadside. Sick children have no treatment here.”

Vivian Tan, the regional spokeswoman for UNHCR, said most of the people coming in are completely exhausted, “some of them say they haven't eaten in days and some are completely traumatized by their experiences.”

According to aid workers, a large number of refugees required immediate medical attention as they were suffering from respiratory diseases, infection and malnutrition.

Satellite imagery analyzed by Human Rights Watch shows that hundreds of buildings have been destroyed across Rakhine state, including nearly 700 structures that were burned down in the village of Chein Khar Li.

The UN believes the Myanmar government’s actions may account to ethnic cleansing and crimes against humanity.
