In remarks delivered at an emergency session on the situation in Sudan at the United Nations Human Rights Council in Geneva on Friday, the top U.N. human rights official called on Sudan’s military leaders to step back following a coup last week.

Michelle Bachelet, the UN High Commissioner for Human Rights, called the Oct. 25 military takeover “deeply disturbing” and demanded an end to the deadly use of force by the armed forces, military police, and intelligence elements, which she said had killed at least 13 civilians.

“I implore Sudan’s military leaders and supporters to take a step back and allow the country to return to the path of progress toward institutional and legal reforms,” she said.
