Refugee Relief and Repatriation Commissioner Mohammad Mizanur Rahman told Prothom Alo that refugee camps No. 6, 7, 9 and 10 are most vulnerable to landslides, and that about 100,000 Rohingya live in these camps.
However, there will not be a need to evacuate everyone. He said that if it rains continuously, there may be a need to evacuate refugees and they have all the necessary preparations.
