DOHA, September 20. /TASS/. US embassies in several Middle Eastern countries have issued a security warning to US citizens, urging them to stay vigilant and keep in mind the unpredictable situation in the region.

The US diplomatic missions in Jordan, Israel, Iraq, Qatar, Bahrain, Saudi Arabia, the United Arab Emirates (UAE) and Lebanon informed that "due to tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation."

"Iranian-supported Houthis have engaged in hostilities against Saudi Arabia, including civilian airports. This military conflict has the potential to escalate rapidly," the alert reads.

"Americans traveling to or from the region should monitor information about airport and airline operations," US diplomats warned. "US diplomatic facilities, including outside the Middle East, have been targeted."

"Iran and groups supportive of Iran may target other US interests overseas or at locations associated with the United States and Americans throughout the world, including U.S. businesses and other institutions," the document reads.
