Saudi authorities announced that schools should remain closed for the entire week, according to messages consulted by the France-Presse agency (AFP), without detailing the reason for this decision.
A Lebanese expatriate residing in the Saudi capital told AFP that it was a sudden decision and that they were unaware of what was happening.
These closures occur after Houthi fighters from Yemen, with Iranian support, launched new attacks against Saudi Arabia on Saturday. The targets of these attacks included Riyadh and Khamis Mushait, a city located in the southwest that houses an important air base.
The Saudi armed forces confirmed that they managed to intercept both drones and ballistic missiles fired from Yemen.
Yemen, which experienced a period of relative calm in recent years, returned to conflict in July, establishing a new area of tension in the Middle East.
The current hostilities involve the Houthis, who control the capital Sanaa and the Yemeni coast on the Red Sea, against the internationally recognized government, which is exiled in Aden (south) and governs much of the south and east of the country, supported by a military coalition led by Saudi Arabia.
On Saturday, Riyadh criticized the alleged failures of the international community in fulfilling its obligations regarding threats from Iran in the Gulf before the United Nations General Assembly.
The Saudi Foreign Minister, Faisal bin Farhane, condemned the 'unjustifiable Iranian aggressions' directed against Saudi Arabia and other nations in the region. He lamented the deficiencies of the international community in responding to threats to global peace and security at a time when the country is under attack by the Houthis.
Faisal bin Farhane also emphasized that 'the stability of this vital region is directly linked to global energy security.'
Saudi Arabia also requested guarantees for freedom of navigation, given that the country's oil exports are being severely impacted by disruptions in the Strait of Hormuz and the Bab el-Mandeb, resulting from the war in the Middle East.
The head of Saudi diplomacy stressed that 'the protection of international navigation and supply chains is a shared responsibility that requires serious international cooperation,' referring specifically to the two straits, the Gulf of Aden, and the Red Sea.
