TEHRAN, Iran — Iranian news reports on Saturday stated that six workers who were badly burned in a gas pipeline explosion have died.
The ISNA news agency also reported Saturday that 20 people were injured.
Friday night's accident was caused by an earth-moving machine that struck a local pipeline, setting off an explosion and igniting a large fire in the northeastern city of Mashhad.
The pipeline brought gas to the city from a nearby refinery. It took firefighters three hours to bring the blaze under control.
