A fuel tanker overturned and exploded in Bangkok
Eyewitnesses to the disaster, which occurred at noon on November 29, captured an explosion and a fireball rising upward.
Two people suffered non-life-threatening injuries and were taken to the capital's Charoenkrung Pracharak Hospital.
Firefighters who arrived at the scene localized the fire within a few hours.
Thailand has one of the worst road safety records in the world. The Transport Ministry has set a goal of reducing the death rate from 32.7 deaths per 100,000 people to 12 by 2027, but insufficient investment in infrastructure appears to be hampering those efforts.
