Saudi Arabia on Saturday confirmed that Yemen’s Houthi rebels tried to attack its capital with a ballistic missile, the first targeting of Riyadh since the escalation in fighting with the Tehran-backed rebels that has opened a new front in the Iran war.

The statement by the Saudi-led coalition fighting the Houthis came long after the dawn attempt, which the coalition said was intercepted. Some residents in Riyadh heard an explosion. Later, some saw a plume of smoke near the airport. There were no reports of casualties or damage.
