The Houthis have been launching attacks on critical Saudi infrastructure.
Talks between the U.S. and Iran remain stalled despite the two countries signing a memorandum of understanding in June, aimed at ending the war that began with joint American-Israeli strikes on the country in February. The opening strikes killed a host of top Iranian officials and commanders, among them Supreme Leader Ayatollah Ali Khamenei.
The two sides have continued to exchange strikes, though have not returned to the intense fighting seen in the early stages of the conflict. The U.S. says it is enforcing a naval blockade of the country's Persian Gulf and Gulf of Oman ports, while Iran claims control over the strategic Strait of Hormuz and continues to claim attacks on shipping transiting the waterway.
Meanwhile, intensified fighting between Saudi-backed Yemeni forces and Iran-backed Houthi rebels in Yemen has seen the latter repeatedly attack Saudi military, oil infrastructure and transport facilities.

Saudi Arabian military spokesperson Col. Turki al-Maliki said in a series of posts to X on Sunday that Saudi air defenses intercepted three Houthi ballistic missiles, two cruise missiles and one drone launched toward Saudi regions.
Two of the ballistic missiles and both cruise missiles targeted the capital Riyadh, Maliki said.
The General Directorate of Saudi Civil Defense on Sunday morning issues safety warnings for the capital city of Riyadh and for the southwestern city of Najran.
Shortly after the warnings were issued, the directorate said the danger had passed in both areas.
The Iran-aligned Houthi rebels in Yemen have been firing missiles and drones toward Saudi cities and critical infrastructure sites in recent months.
The Navy of the Islamic Revolutionary Guard Corps (IRGC) said in a statement on Saturday that two oil tankers had exploded and were on fire after striking mines in the east of the Strait of Hormuz, the Islamic Republic News Agency reported.
The IRGC accused the two tankers of attempting to transit via an "unauthorized route" and of deactivating their navigation and positioning systems.

U.S. forces fired at a cargo vessel attempting to break the U.S. blockade of Iranian ports, according to U.S. Central Command.
CENTCOM said an aircraft fired munitions at the stern of the M/V Huda to disable it. This is the 11th ship CENTCOM has disabled since it began the blockade in July.
Earlier Saturday, CENTCOM announced the establishment of a 20 person team called "Task Force Iron Gate" that will work with other agencies to prevent Iran from using land routes to transport advanced weapons.
