Based on my research, I can verify this claim:

Reasoning:

• A U.N. report by the Commission on Human Rights in South Sudan (CHRSS) alleges that joint aerial bombardments by South Sudan and Uganda "targeted civilian-populated areas predominantly affecting Nuer communities in opposition-affiliated areas"¹
• The report documents an attack in March 2025 in Wunaliet where "homes were engulfed after planes dropped 'barrels of liquid that ignited,'" and survivors reported seeing "civilians set alight, including a boy burnt beyond recognition"¹
• The AP News article specifically states: "Uganda helped South Sudan carry out airstrikes that killed and badly burned civilians," according to the U.N. inquiry¹
• The U.N. report found "high degrees of planning, operational integration and command-level authorization" between South Sudan and Ugandan forces regarding the air operations¹
• Flight tracking data confirmed a turboprop plane that circled the bombing area had arrived from Uganda and was operated by the Ugandan army¹

The claim accurately reflects the contents of the U.N. report, which documents joint South Sudan-Uganda airstrikes that destroyed homes and harmed civilians.

Overall validity: 95%
