Authorities in Saudi Arabia said they're conducting an investigation into an incident that left an oil pipeline in the eastern part of the country ablaze.

The Saudi Press Agency reported authorities were able to control the blaze that erupted after a stray bullet hit the pipeline early Saturday. Local police said they conducted an investigation into the incident that followed a clash between area assailants and a security patrol.

A 2012 report from Press TV, a broadcast agency controlled by Saudi adversary Iran, attributed a pipeline explosion in eastern Saudi Arabia to a substantial rise in crude oil prices.

The report said a pipeline designed to carry as much as 6 million barrels of oil per day to the Ras Tanrua oil terminal was destroyed, though the account was later said to be fabricated.

The Saudi press report provided no data on pipeline capacity or details about the clash with area assailants.
