The strikes reportedly followed an Iranian attack targeting a U.S. aircraft. Officials described the operation as defensive rather than a return to large-scale combat.
U.S. officials said the strikes targeted Iranian surface-to-air missile systems being used against American assets in the Strait of Hormuz.
Iranian state television reported that explosions were heard on Qeshm Island.
The incident comes as Qatar-mediated diplomatic efforts continue to seek an agreement between Washington and Tehran, leaving markets sensitive to any sign of renewed escalation near the critical oil-shipping route.
