Six people have been injured in an explosion at an oil refinery in Iran coinciding with a visit by President Mahmoud Ahmadinejad, Iranian media say.
He was not hurt in the blast and went on to make a televised speech to mark the opening of the refinery, in the south-western city of Abadan.
A technical problem caused the blast and then a fire, Fars news agency said.
Thick smoke was seen rising from the refinery but the fire was under control, the semi-official agency said.
The refinery is being launched in two phases and ultimately will produce more than 6m litres of petrol a day, mostly for domestic consumption.
