The United Nations humanitarian chief, Tom Fletcher, and the Humanitarian Coordinator for Sudan, Clementine Nkweta-Salami, on Thursday welcomed the news that the crucial Adre crossing between eastern Chad and the western region of Darfur in Sudan will remain open for the movement of humanitarian personnel and life-saving supplies.
