The fire broke out after an explosion in a large fuel depot and quickly spread to nearby houses. Residents have described how they felt a strong smell, so strong that many vomited, and then heard a rumbling sound followed by an explosion.
Around 35 people are still being treated in hospital, some of them with serious injuries, and more than 1,300 people have been moved to temporary shelters.
A preliminary police investigation shows that the fire was caused by technical problems with the pressure when refueling at the depot.
