The International Criminal Court’s chief prosecutor asked judges on Wednesday to issue an arrest warrant for the head of Myanmar’s military regime for crimes committed against the country’s Rohingya Muslim minority.

The warrant is a moral victory for the Rohingya, but will do little to change the actions of the Myanmar military on the ground, observers said.

ICC chief prosecutor Karim Khan alleged that Senior Gen. Min Aung Hlaing “bears criminal responsibility for the crimes against humanity of deportation and persecution of the Rohingya” in both Myanmar and parts of Bangladesh between August 25 and December 31,
