BBC Verify has identified what appears to be damage to a storage unit at the Abadan Oil Refinery based in the south-western province of Khuzestan.
However, we don’t know what caused it and there is likely to be damage in some areas across Iran caused by debris or misfiring defence systems.
The New York Times cited Israeli officials , externalas saying that the Abadan oil refinery was one of the sites targeted in its air strikes on Saturday morning.
Iranian authorities confirmed on Saturday that Khuzestan province had been targeted by Israel.
Abadan oil refinery is the country’s largest, capable of producing 500,000 barrels a day, according to its chief executive, external.
Satellite imagery isn’t always conclusive in identifying damaged structures.
For example, a photograph we have verified showing smoke rising near Hazrat Amir Brigade Air Defence base suggested it had been successfully targeted. But satellite imagery of the area captured on Sunday has too many shadows to confirm any damage to the site.
Iran launched a missile attack on Israel at the start of October for the second time this year, after firing 300 missiles and drones in April.
