Gambia filed a case Monday at the United Nations’ highest court accusing Myanmar of genocide in its campaign against its Rohingya Muslim minority and asking the International Court of Justice to urgently order measures “to stop Myanmar’s genocidal conduct immediately.”

Gambia filed the case on behalf of the Organization of Islamic Cooperation.

Gambia’s justice minister and attorney general, Abubacarr Marie Tambadou, told The Associated Press he wanted to “send a clear message to Myanmar and to the rest of the international community that the world must not stand by and do nothing in the face of terrible atrocities that are occurring around us. It is a shame for our generation that we do nothing while genocide is unfolding right before our own eyes.”

Myanmar officials did not immediately respond to requests for comment.

Myanmar’s military began a harsh counterinsurgency campaign against the Rohingya in August 2017 in response to an insurgent attack. More than 700,000 Rohingya fled to neighboring Bangladesh to escape what has been called an ethnic cleansing campaign involving mass rapes, killings and the torching of homes.

The head of a U.N. fact-finding mission on Myanmar warned last month that “there is a serious risk of genocide recurring.”

The mission also said in its final report in September that Myanmar should be held responsible in international legal forums for alleged genocide against the Rohingya.
