Here are all the countries now involved in the Iran conflict - Axios

U.S. embassies across the region remain on high alert and the State Department is urging Americans to leave immediately, including ordering diplomats and staff out of Saudi Arabia. The widening geographic footprint of strikes and associated airspace restrictions has broadened the conflict, prompting embassy closures and complicating coordination with regional partners. The attack on a British base in Cyprus shows the conflict is now affecting EU territory, intensifying travel and security concerns for European governments and potentially expanding the list of countries directly involved.
