An independent fact-finding mission will investigate reported mass killings in the Sudanese city of el-Fasher, the UN announced on Friday.

There has been too much pretence and performance, and too little action from the international community in the face of Sudan's devastating civil war, UN human rights chief Volker Türk said at an emergency meeting in Geneva.

He stated, It must stand up against these atrocities - a display of naked cruelty used to subjugate and control an entire population, warning those fuelling and profiting from the civil war.

More than 150,000 people have been killed, and about 12 million have fled their homes due to the violence.

As part of the investigations, experts will also seek to identify perpetrators in order to hold them accountable.

El-Fasher was captured last month by the Rapid Support Forces (RSF) following an 18-month siege, becoming the last city in Darfur held by the army and its allies.

The RSF faces accusations of targeting non-Arab groups in the city and elsewhere in Darfur, claims they have denounced.

A disturbing factor in this ongoing conflict has been the volume of shocking footage and photographs of violence, often shared online by the culprits themselves. Researchers plan to analyze this digital evidence to pursue justice.

UN mission member Mona Rishmawi, reflecting on her extensive experience, remarked that the current scale of suffering in Darfur is greater than the Janjaweed genocide of 20 years ago. She pointed out that the RSF originated from the Janjaweed, and unlike past attacks focused on villages, current aggressions are against entire cities and refugee camps.

Recent joint statements by the G7 condemned the surging violence, branding the situation a humanitarian crisis of unparalleled magnitude.

Meanwhile, concerns mount around the flow of arms into Sudan amid the conflict. Reports indicate that arms supplied from various countries, including Serbia, Russia, Turkey, and the UAE, have been utilized in the ongoing violence, raising questions about international complicity in the unrest.

Efforts for peace are complicated by conflicting interests among nations and factions, with calls for humanitarian truces and subsequent transitions to civilian rule facing significant obstacles.
