Saudi Arabia said Saturday that Yemen’s Houthi rebels attempted to attack the capital, Riyadh, with a ballistic missile, according to NPR. The Saudi statement identified the Houthis as responsible for the reported attack.

NPR reported that the incident would mark the first time Riyadh had been targeted since an escalation in fighting with the Iran-backed rebels. The escalation has opened a new front in the Iran war, the broadcaster said.

The supplied report did not provide details about when the missile was launched, whether it was intercepted, or whether the attack caused casualties or damage. It also did not include a response from the Houthi movement.

Saudi Arabia and the Houthis are parties to Yemen’s conflict, which has periodically threatened to spill beyond the country’s borders. In the information provided, however, no further details were available about the circumstances of the reported launch or its wider consequences.
