The number of fatalities in Saturday's explosion at Shahid Rajaei port in southern Iran is in the dozens, local sources told Iran International.
Earlier Iran’s state broadcaster IRIB reported that only four individuals were killed in the blast.
The figures announced officially account only for those who were in the surrounding areas, not at the heart of the explosion, a source familiar with the situation told Iran International.
A source close to the family of one of the victims, who shared images and videos from the site with Iran International, said: "Why does the Islamic Republic insist on claiming that no one was killed or that the number of deaths is low?"
Hundreds have been injured, and hospitals lack the capacity and resources to treat them, a family member of an injured person told Iran International, speaking outside a hospital in Bandar Abbas and sharing video footage.
Another Iran International viewer sent a video showing the body of a coworker lying among trucks at the site.
