Iranian experts have repaired three major gas pipelines that exploded in central province of Qom on Friday, says the chairman of Iran's Gas Transportation Company.
“Utilizing essential tools and resources, the personnel of National Gas Company made repairs to the damaged gas pipelines within less than 24 hours,” Mehr news agency quoted Reza Almasi as saying on Saturday.
Almasi added that a probe is under way to discover the cause of the incident.
An explosion ripped through three 56-inch (142-centimeter) diameter gas pipelines on Friday around the town of Delijan in Iran's Qom province.
The blast temporarily disrupted gas delivery from refineries in southern Iran to the north and northwest.
Rescue and maintenance teams were immediately dispatched to the region in order to monitor the situation.
Iran has the world's second-largest natural gas reserves after Russia.
