Firefighters worked to put out a blaze after a pipeline carrying crude oil to Iran’s second-largest refinery ruptured and burst into flames on Sunday, Reuters reports referring to Iranian news agencies.
“The fire has not been contained but is under control. Its smoke is irritating, but it is not enough to injure anyone, and flames have not reached people’s homes,” Khosro Kiani, an emergency official in southwestern Iran, where the blaze occurred, told the semi-official news agency Tasnim.
Kiani said the oil had spilled down a hard-to-access valley, which firefighting equipment could not reach.
The oil ministry’s news agency SHANA said repair teams had shut off the Maroun pipeline, which feeds the Isfahan refinery, Iran’s second-largest with a capacity of about 375,000 barrels per day.
Iran’s aging oil infrastructure has been long in need of rehabilitation, as Western sanctions and local bureaucracy have delayed refurbishment plans, analysts say.
Several earlier instances of spillage from the pipeline have adversely affected the region’s agriculture and fishing, the state news agency IRNA reported.
