The UN High Commissioner for Human Rights, Volker Türk, on Monday, called on Malian authorities to rescind their expulsion order for his top representative in the country.
Mr Ngefa, Director of the Human Rights Division of the UN Stabilisation Mission in Mali (MINUSMA) and Representative of the High Commissioner in Mali, had been declared persona non grata in an announcement by Malian authorities on Sunday.
Ngefa was already outside Mali when the decision was announced.
