Iranian media reported that the former US Embassy building in Tehran was targeted in an attack early on Wednesday, and said the United States had struck the site.
According to witness accounts cited by the reports, the eastern side of the compound at the intersection of Taleghani and South Mofatteh streets was damaged.
Officials have not yet released details about the attack or the extent of the damage.
The former US Embassy was turned into a museum after it was seized in November 1979 and has since been largely controlled by institutions linked to the Revolutionary Guards and the Basij.
