Aid workers on donkeys have delivered the first humanitarian supplies to survivors of a landslide that reportedly killed hundreds of people in a remote mountain village in Sudan's western Darfur region.

Heavy rains and flash floods that hit Tarasin village triggering the disaster on Sunday have continued, meaning donkeys are the only way to reach the affected families.

Families in Tarsin have lost everything. It took our team more than a full day on a rocky, muddy, and hilly route to reach this devastated community, said Francesco Lanino, from aid agency Save the Children.

The armed group in charge of the area put the number of casualties at 1,000, however the health ministry says only two bodies have been recovered. Local civilian leaders reported the recovery and burial of hundreds, with many still trapped.

The SLM/A has urged for urgent international intervention to address the catastrophic humanitarian situation in Tarasin.

The ongoing conflict in Sudan has severely hampered rescue efforts, according to another aid organization, World Vision. Hundreds of lives have been lost, and communities are shattered. Aid workers are racing against time and challenges to reach the most vulnerable.

As at least 21 areas across Sudan face similar heavy rains and floods, experts warn of potential disease outbreaks, compounding the already dire humanitarian crisis in a nation where 30 million people are in need of assistance.
