Iran’s Islamic Revolutionary Guard Corps (IRGC) has claimed responsibility for a missile and drone attack on a petrochemical complex in Jubail, an industrial city in Saudi Arabia’s Eastern Province. The IRGC said the strike targeted facilities belonging to American companies including Sadra, ExxonMobil, and Dark Chemical. It described the operation as retaliation for an earlier Israeli attack in Shiraz.

According to the report, the IRGC also stated that it targeted another petrochemical complex in Juaymah owned by the American company Shordan Phillips. The attack followed warnings from Iranian officials that any assault on Iran’s power plants or bridges would be met with similar responses against regional infrastructure. The report noted that former U.S. President Donald Trump had set a deadline for reopening the Strait of Hormuz, threatening escalation if unmet.

The Saudi government has not yet issued any official comment on the incident, and details about the extent of damage or the specific weapons used remain undisclosed.
