A devastating war in Sudan has left 800,000 people trapped in El Fasher in the west of the vast country, UN humanitarians warned on Friday, as they reiterated calls for an immediate ceasefire to allow lifesaving aid in. The development comes as disturbing details continue to emerge of an alleged attack on the village of Wad Al-Noura in Jazira state south of Khartoum which left more than 100 dead, including dozens of children. To find out more, UN News’s Daniel Johnson spoke to Jill Lawler from the UN Children’s Fund, UNICEF. She’s working in Sudan and knows the area where the attack took place well.
