Saudi Arabia once again put the holy city of Mecca under emergency alert on Thursday, warning of "potential danger", according to the directorate of Saudi Civil Defence.
"A warning has been issued by the National Early Warning Platform in Mecca City to alert of a potential danger," read the tweet by the defence agency.
Other regions under alert included the Jeddah and Yanbu governorates and the Tabuk province.
The security agency directed citizens and expatriates to follow official instructions. It advised people to stay inside a building, ideally away from windows and glass, until the danger passes. They were also urged to avoid open areas, balconies and rooftops. Those who were outside were directed to move to a nearby building or behind a solid barrier.
The Saudi Civil Defence also instructed people to avoid crowds and refrain from filming.
On September 18, Saudi issued alerts for Mecca for the first time in history. Taif, Khamis Mushait and Al Ula province were also put under alert.
The Houthis had denied the Saudi allegations about trying to attack Mecca after the September 18 alert. The Iran-backed proxies were yet to respond to the latest alerts on Mecca when this article was published.
Two days later, Saudi authorities confirmed that Houthis tried to attack Riyadh with a ballistic missile. However, there were no reports of casualties or damage.
Saudi Arabia has reportedly sought air defence support from Pakistan and Egypt, but it is not clear if Riyadh received any supplies in this regard.
