Following the first leg of the AFF Cup final, in which Vietnam defeated Thailand 3–0, millions of Vietnamese poured into the streets to parade and celebrate. This man reportedly set himself on fire after placing a bet on Thailand. Bystanders tried to extinguish the flames with water, a flag, and finally a fire extinguisher. This is the initial video footage of the incident. It occurred on the night of August 22, 2026, at 30/4 Park next to Notre Dame Cathedral in Ho Chi Minh City, Vietnam.
