Iran expects most units at its Bu Ali Sina petrochemicals complex to resume operations within three weeks, after a fire was extinguished early on Saturday, Oil Minister Bijan Zanganeh was quoted as saying by his ministry's website, Shana.

"The paraxylene tower will take longer to get back (online)," Zanganeh said, adding that the rest of the plant would be restarted in two to three weeks, Shana said.
