Human rights groups in the Sudanese region of West Darfur are reporting further ethnic-based killings by Arab militias and the paramilitary Rapid Support Forces (RSF).
People are continuing to flee into Chad – some with gunshot wounds.
The UN children’s agency (Unicef) says more than a quarter of a million children have recently been displaced in Darfur.
People fleeing from Sudan into Chad say they have suffered appalling atrocities when attacked by the RSF and its allied militias.
At checkpoints on the way to the border gunmen are extorting money. Human rights activist say there has been widespread sexual violence and killings based on ethnicity.
Satellite images show that parts of El Geneina city and entire villages in Darfur have been razed to the ground.
The US State Department says there is a pattern of targeted ethnic violence against non-Arab populations, with credible evidence that the RSF has destroyed entire villages and carried out rapes and murders.
In many ways the violence is a continuation of what happened in Darfur 20 years ago.
It is being widely condemned but no-one seems to have any idea how to stop it.
