After Israel and the US began operations Roaring Lion and Epic Fury on Saturday, the National Security Council issued a warning to Israeli citizens abroad to take increased precaution "at all destinations around the world" due to the risk of Iranian retaliatory attacks.
"Given past experience, it is possible that other terrorist elements and local initiatives (including individual attackers) will be motivated to harm Israelis abroad," the NSC wrote.
It also called on the public to heed travel warnings and to check a country's travel warning in advance of departure.
