About 2,200 of the 720,000 Rohingya Muslims who fled persecution, organised slaughter and rape in their homeland of Myanmar last year, are being sent back.

It is a process that has been repeatedly delayed, and one that few, apart from the Myanmar and Bangladesh governments, think is a good idea.

On Tuesday, the UN high commissioner for human rights, Michelle Bachelet, warned that forcing the first batch of Rohingya living in refugee camps in Bangladesh to return to ground zero of mass violence against the minority Muslim group would be a “clear violation” of core international legal principles.
