Saudi Arabia's national oil company, Aramco, now says a pipeline fire that erupted last Sunday killed 40 people, including six Saudis. Nine workers were hospitalized. Six have been treated and released.
Aramco says the blaze started early Sunday morning while workers were performing maintenance on a natural gas pipeline 30 kilometers from the Hawiyah gas plant.
The fire coincided with the OPEC summit taking place in the capital, Riyadh.
Officials say they have ruled out any possibility of the fire being part of a terrorist attack.
The fire did not disrupt gas supplies.
