• International Human Rights groups are opposing the relocation of Rohingyas to the Bhashan Char.
• They demand independent assessment of the liveability on the Bhashan char by the UN and humanitarian agencies before the process is started.
• Bhashan char
• It is an uninhabited island where the government of Bangladesh has made shelter houses for one lakh Rohingya refugees at an estimated cost of Tk. 2,300 crore.
• The environmentalists say that the Bhashan char falls in an ecologically fragile area prone to floods, erosion and cyclones.
• Currently more than a million Rohingya are living in refugee camps in Bangladesh after fleeing the military crackdown in the Rakhine province of Myanmar in August 2017.
