4 killed at petrochemical factory
TEHRAN — An explosion in a petrochemical factory at a large oil terminal has killed four people, the nation’s official news agency said. High pressure in the central boiler of the factory led to an explosion and a fire at the facility on Khark island in the Persian Gulf. The bodies of three of the victims were found and the blaze was under control. Several other workers were injured. Khark Island, about 750 miles south of Tehran, has Iran’s biggest oil terminal in the Persian Gulf. Iran is the Organization of Petroleum Exporting Countries’ second-largest oil exporter, producing about 4.2 million barrels of oil per day.
