Saudi Arabia has said it had intercepted a ballistic missile fired at an air base southeast of the capital Riyadh, as Iran pressed attacks across the Gulf.

"A ballistic missile launched towards Prince Sultan Air Base was intercepted and destroyed," the Saudi defence ministry posted on X.

Israel has said it had launched "broad-scale" attacks on targets in Tehran, as the Iranian state broadcaster reported an explosion in the western part of the city.

"The IDF (Israeli army) has begun a broad-scale wave of strikes" on government targets in the Iranian capital, an Israeli military statement said.

The Israeli military said earlier it had detected another round of Iranian missile fire headed towards Israel.

A series of explosions were heard in Tel Aviv following the Iranian launches.

Israel's emergency services said it received no reports of casualties after the barrage.

The military issued a statement saying people were free to leave their shelters "in all areas of the country."

US Secretary of State Marco Rubio has told Arab foreign ministers that the US-Israeli war on Iran could last "several more weeks" and that Washington is not seeking "regime change," according to a report.

Sources with direct knowledge of the conversations told the Axios news site that Rubio made the remarks during calls on Thursday with Arab foreign ministers.

Rubio said the military focus is on Iran’s missile launchers, stockpiles and factories, according to the report.

Rubio also told the ministers that the US goal is not "regime change," while simultaneously signaling that "Washington wants different people running the country", the sources reportedly said.

He added that there is currently no US dialogue with the Iranian government and argued that any talks at this stage would undermine military objectives.
