President Joseph Kabila of the Democratic Republic of Congo has visited survivors of the weekend’s devastating fuel explosion which killed at least 250 people.
Experts are warning of similar accidents unless the government tightens safety measures in the chaotic eastern and southern regions.
Private companies are used to deliver oil but often use poorly maintained vehicles on the crumbling roads.
More than 60 children, many watching football in makeshift cinema halls, were among those killed in the blast after an oil tanker toppled and leaking petrol later exploded.
Others died while attempting to scoop up the spilled fuel.
Very little is left of the surrounding homes after the blast, which is said to have been the equivalent to over 300 kilograms of dynamite.
President Kabila has called for a full inquiry into the tragedy.
