Last month Gambia, a small West African country that is mostly Muslim, brought a lawsuit against Myanmar at the International Court of Justice (ICJ). The lawsuit alleges that Myanmar committed genocide, including mass murder and rape against the Rohingya minority of Rakhine State.
Myanmar of course denies the claims saying the in September of 2017 the military action was to respond to terrorists who had earlier killed 13 security officers on the border. Militant Rohingya were attempting to get military security out of the region and to create their own region.
There was a lot of misinformation according to the Myanmar government on what had happened. Regardless, over 700,000 Rohingya people ended up on the Bangladesh border creating the largest refugee camp in the world.
