Declan Walsh reports for The New York Times that Lana Zaki Nusseibeh, a leading candidate for United Nations secretary general, has for years led Emirati efforts to deny her country's role in Sudan's civil war, where it is accused of arming the Rapid Support Forces. U.N. investigators found the Emirates hired Colombian mercenaries through an Abu Dhabi security company tied to the ruling family, and critics like Human Rights Watch say her record of "whitewashing" abuses should disqualify her; she denies the allegations and pledges ending the conflict would be her priority.
