True
A festival in Colombia in which a bull's horns are set on fire has drawn criticism from animal rights groups, with the practice described as animal abuse, according to animal advocacy organization reporting cited in the claim.
The festival centers on attaching flaming material to a bull's horns and releasing the animal amid crowds, a spectacle that animal rights activists have singled out as cruelty. An organization called Organización Animalista appears among the sources documenting the controversy, though its detailed report could not be accessed due to a connection timeout, leaving the full scope of its findings unreviewed.
The claim's core assertion — that a Colombian festival involves setting fire to a bull's horns and has triggered an animal abuse controversy — stands as fact based on the sources consulted.
Specific details about the festival's location, dates, and the response from Colombian authorities or festival organizers were not available in the material reviewed. The animal rights organization's full documentation of the event likewise remained inaccessible.
Overall, the claim that a Colombian festival involving a bull with burning horns has become the subject of an animal cruelty controversy is assessed as true. Verdict: True
