Saudi Aramco evacuated its headquarters following an alarm there and authorities have asked staff to work remotely, according to a new report.

It is not clear how long the order will last and the reason for the alarm wasn't immediately known, people familiar with the matter told Bloomberg.

Aramco's headquarters had already been hit last week. The building in question is located in the Eastern province city of Dhahran and happened after Riyadh said it intercepted three cruise missiles and two drones heading into the region.

The U.S. also ordered some diplomats and family members to leave its mission in the country after an attack killed at least one person and injured eight more at an airport in Dammam. In a separate incident, two people were killed in a drone attack.

"The U.S. Department of State issued an ordered departure for non-emergency U.S. government employees and their family members in Saudi Arabia only. Iranian-supported Houthis have increasingly engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure resulting in civilian casualties and severe travel disruptions," State Department spokesperson Tommy Pigott said in a social media publication on Wednesday.

Several countries have pledged their support for Riyadh as it grapples with escalating attacks from the Houthis. A Turkish official told Reuters that the government will seek parliamentary approval to send military personnel to the country as part of its newly-signed defense pact with Riyadh and Islamabad.

A lawmaker for the ruling AK Party told the outlet that the mandate will be sent to parliament once the accord ratifying the pact is approved. equipment, intelligence sharing and weapons systems.

The country submitted the Mecca Joint Defence Agreement to parliament on Tuesday. The country also signed an agreement with Qatar, Pakistan and Indonesia to boost defense cooperation and defensive capabilities. It is called the "Badr Memorandum of Understanding."

"By leveraging the unique military production capabilities of each country, ​the initiative will facilitate cooperation and integration, enhance defense industrial capacities, and enable ​the fulfillment of the needs of allied and friendly nations," the Turkish Defense Ministry said in a statement.

Turkey's initiative comes shortly after the UK increased the amount of military support sent to Riyadh. London noted that it will send fighter jets to perform defensive operations, also providing refueling support on actions that include strikes against Houthi targets.

Pakistan, in turn, has sent about 8,000 troops and air force fighter jets to conduct strikes, according to another report. Troops, however, are unlikely to engage in any fighting and will be tasked with defending Saudi oil infrastructure.

More than 70 people died in Yemen after the Houthi rebels launched their latest attacks against against government forces. The strike took place in a military camp in the southern province of Shabwa. Some 200 people were wounded as well.
