The Houthis again threatened Aramco facilities.
The Saba news agency, which is linked to the Houthis, quoted an anonymous military source as saying: "Aramco's facilities are within range of Yemen's armed militant forces, and investing in them is harmful."
This official also warned international airlines against crossing Saudi Arabia's airspace "except for the airspace of Mecca and Medina."
Since the rekindling of war in Yemen in July, the Houthis have launched drone and missile ground attacks on oil facilities and airports in Saudi Arabia, declaring the country's airspace a war zone.
Meanwhile, the war continues in the southwestern regions of Yemen, and the city of Taiz is under siege by the Houthis.
The Houthis, who are allies of Iran, are fighting with the Saudi-led coalition.
The United Nations said today that more than 300,000 people have been displaced from their homes in the West by the war.
