One of the few NGOs operating in Sudan's Darfur said the group, along with the UN, are planning to deploy teams to a remote village devastated by a landslide in the coming days, but deployment remains difficult due to heavy rain, making roads inaccessible.

Arjimand Hussain, the Plan International's Response Manager for the Sudan Crises, said it has been very challenging to reach Tarasin which - according to a rebel group - has been wiped out by a devastating landslide over the weekend in the western region of Darfur.

“Neither any international humanitarian agency or any UN agency has been able to reach there considering the challenges of access, the rains, and also the flooding and the flash floods in the valleys on the way,” he said.

The Sudan Liberation Movement Army said the death toll from the Aug. 31 landslide in Tarasin, in the Marrah Mountains, could be as high as 1,000.

The UN said that “between 300-1,000 people may have lost their lives” in the landslide and efforts were mobilized to support the impacted area, located more than 900 kilometers (560 miles) west of the capital, Khartoum.

The Marrah Mountains region is a volcanic area with a height of more than 3,000 meters (9,840 feet) at its summit.

The mountain chain is a world heritage site and is known for its lower temperature and higher rainfall than its surroundings, according to UNICEF.
