A fire which broke out on Wednesday at an oil product pipeline north of Riyadh during repairs has been extinguished, state news agency SPA and security sources said.

The pipeline was carrying diesel, not crude oil, an industry insider said. One security source said that the accident, which took place near Sudair area some 250 km north of Riyadh, was “not the work of terrorists.”

Speaking by telephone from Riyadh, the source said a contractor was trying to fix the pipeline and “it broke.”

Similar details were reported later by the Saudi state news agency SPA which said authorities had put out the fire and were working to deal with the flow of products at the scene.

“The accident did not result in any injuries or death,” SPA cited Maj. Mohammed Al-Hammadi, spokesman of the Civil Defense team in Riyadh as saying.

A US security source said that a US government assessment found that the fire was caused by faulty repair work.
