A senior United Nations official has criticized international efforts to resolve Sudan's ongoing war as inadequate, as the conflict approaches its third anniversary next month.

Denise Brown, the top UN official for Sudan, described the global response as "unacceptable" in comments to The Guardian, expressing concern over what she characterized as insufficient political urgency to end the conflict.

The war has displaced approximately 14 million Sudanese people from their homes, according to UN figures. Tens of thousands of people remain missing as the conflict continues.

Recent reports indicate that Sudan is experiencing what has been described as the world's largest humanitarian crisis, with conditions continuing to deteriorate as the war extends into its third year.

Brown's criticism comes as international diplomatic efforts to broker peace have yet to produce a lasting ceasefire or political resolution to the conflict that began in April 2021.

The humanitarian situation has drawn increasing concern from international organizations as displacement figures continue to rise and access to affected populations remains challenging.
