Saudi Aramco has ordered the evacuation of all remaining staff from its headquarters in Dhahran, eastern Saudi Arabia, and instructed employees to work remotely until further notice, various news channels have reported quoting sources.

The move comes as the energy giant steps up measures to protect its workforce following a series of Houthi attacks on its facilities.

The decision extends earlier precautionary measures under which non-essential personnel had been working remotely since the sprawling headquarters complex was hit last week, according to sources familiar with the matter.

The latest directive covers remaining essential staff, effectively suspending on-site office operations at the headquarters while allowing employees to continue their duties remotely.

The sources, who spoke on condition of anonymity for security reasons, said residential areas within the sprawling Dhahran complex had not been closed or evacuated.

The move comes amid heightened security concerns in Saudi Arabia's Eastern Province, home to much of the kingdom's oil industry and several of Aramco's key operational facilities.

The evacuation order followed a late-night attack on Dammam airport, also in eastern Saudi Arabia.

Saudi air defences intercept missile, drones

Meanwhile, Saudi-led coalition forces reported intercepting further Houthi attacks targeting different parts of the kingdom.

Major General Turki Al-Malki, official spokesperson for the Coalition to Restore Legitimacy in Yemen, said Saudi air defences had intercepted and destroyed a ballistic missile launched by the Houthis towards Riyadh.

In a separate statement carried by the Saudi Press Agency (SPA), Al-Malki said two unmanned aerial vehicles launched by the group towards Saudi Arabia's Southern Region had also been intercepted and destroyed.

The incidents come amid continued Houthi attacks on Saudi territory, placing additional pressure on security arrangements around major economic and civilian infrastructure.

Coalition rejects Houthi allegations

In a related development, Al-Malki categorically rejected Houthi allegations that Saudi Arabia had threatened to target tribal and civilian gatherings in Yemen, describing the claims as false and baseless.

He said the allegations were part of attempts to mislead public opinion, divert attention from the Houthis' own activities and draw Yemeni tribes into the conflict.

Al-Malki stressed that Yemeni tribes remained an integral part of Yemen's social and historical fabric and an important link between the Saudi and Yemeni peoples.

He said the longstanding ties between the two countries, rooted in religion, geography, history and shared interests, could not be undermined by disinformation or attempts to create divisions.

The coalition spokesperson reaffirmed Saudi Arabia's commitment to Yemen's security and stability and to preserving its historic relationship with the Yemeni people.

He also emphasised the importance of preventing Yemeni tribes from being drawn into conflicts that would undermine their aspirations for security, peace and development.
