Sudan has assured the United Nations that it will not expel any more aid agencies from Darfur, Reuters reports.

“We have received assurances that there are no more expulsions in the pipeline,” John Holmes, U.N. undersecretary-general for humanitarian affairs, told the news service.

Sudan booted 13 foreign-aid organizations and three local groups from strife-torn Darfur earlier this month, deepening the humanitarian crisis in the region. The government claims the groups collaborated with the International Criminal Court’s effort to arrest President Omar Hassan al-Bashir on war-crimes charges.
