A forensic close-up image depicts a contained combustion event

A forensic close-up image depicts a contained combustion event. A prominent, undulating flame, radiating yellow and orange light, is centrally positioned within a dark environment. To the left and beneath the flame, irregular, dark solid fuel fragments, consistent with wood or charcoal, are observed. The fire is contained within a circular, reflective vessel, likely metallic, visible along the right and bottom edges, which reflects the flame's luminescence. Scattered particulate residue is present on the vessel's interior surface. The background is black, indicating complete darkness. No human subjects or their actions are discernible. The scene is situated in Keffi, Nigeria.
