Israeli warplanes has fired missiles on Iran during a retaliatory strike.
One Western official and two Iranian officials said, suggesting that the attack included more advanced firepower than initial reports indicated.
It was not immediately clear the types of missiles used, from where they were fired, whether any were intercepted by Iran’s defenses or where they landed.
The Western official and the Iranian officials requested anonymity to discuss classified information.
Previously, Iranian officials said Friday’s attack on a military base in central Iran was conducted by small aerial drones, most likely launched from inside Iranian territory. A separate group of small drones, they said soon after the attack, was shot down in the region of Tabriz, roughly 500 miles north of Isfahan.
