Iranian media reported early Wednesday that there was a massive explosion on a major gas pipeline in the city of "Borujen" in southwestern Iran.

The blast, which affected (Line 65) of the main gas pipeline, was heard up to approximately 60 kilometers away from the incident’s site.

Iranian state television quoted the city's governor, Fattah Karami, as saying that the incident is likely caused by an explosion in the high-pressure national gas pipeline.

He added, "The pipe connection between Borujen, Lorestan, and Khuzestan affected by the explosion has been closed, while rescue and firefighting teams are deployed at the scene."

Iranian channel "Khabar" cited a security source stating, "The fire will continue to expand as long as there is gas in the pipeline, and we hope the efforts of the firefighters will be fruitful." The source emphasized that "it is currently impossible to determine the nature of the event, whether it was an Israeli act or an accidental incident."
