Seven people were injured in an explosion at a South African crude oil refinery in Durban earlier on Friday morning, but no deaths have been reported, a spokesman for the KwaZulu-Natal province's emergency medical services told Reuters.
The injured people are in a stable condition, and the fire at the refinery is under control, spokesman Robert McKenzie said.
A spokesman for Engen, which operates the refinery, said he would comment later in a statement.
According to Engen's website, the Durban plant has a crude refining capacity of 120,000 barrels per day.
It was not immediately clear if there was any impact on the refinery's production.
Africa's most industrialised economy has six refineries, four using crude oil and two synthetic fuel as feedstock. It is a net importer of petroleum products.
