AFP reported, citing a diplomatic source:

#BREAKING US embassy staff and families ordered to leave Saudi Arabia, with families of embassy staff in the United Arab Emirates, Jordan, Qatar and Bahrain also ordered to leave, diplomatic source tells AFP

State Department spokesperson Tommy Pigott disputed the AFP report:

This is inaccurate. 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.

The safety and security of Department personnel and their families remain our highest priority, and we will continue to take all necessary steps to protect and support them.
