The United States has issued a cautionary note around the world, warning Americans to remain vigilant as the conflict involving Iran continues to escalate.
In a notice issued on Sunday, the US State Department urged citizens, especially those in the Middle East, to exercise “greater caution” citing potential dangers associated with the ongoing war.
The department warned that groups linked to Iran could target US interests and locations associated with Americans globally.
It also said that some US diplomatic facilities outside the Middle East have already been targeted.
The alert highlighted the potential for travel disruption, saying airspace could be closed intermittently as the conflict continues.
Americans abroad are advised to follow instructions from their nearest U.S. Embassy or Consulate and stay updated on local security conditions.
The warning comes as the US and Israeli military campaign against Iran enters its fourth week. Iran has responded with drone and missile attacks targeting Israel, Jordan, Iraq and Gulf countries that host US military bases.
