The U.S. Embassy in Israel has issued a warning to Americans to stay on the alert “in the event of mortar or rocket fire.”

The U.S. Embassy in Israel’s website posted a security alert Monday “out of an abundance of caution.” The warning addressed U.S. citizens in Israel, including Jerusalem and Judea and Samaria, as well as those in the Hamas-controlled Gaza Strip, which is home to several terror groups supported by Iran.

Tensions in the Middle East have been at a boiling point since the U.S. killed a Iranian arch-terrorist Qassem Soleimani last week in Iraq.

Israel, a key U.S. ally and longtime foe to Iran, has kept a low profile since the killing.

The U.S. has said it will bomb Iran if Tehran retaliates.

A former Iranian Revolutionary Guard leader then threatened to “level” the Israeli cities of Tel Aviv and Haifa should the U.S. strike Iran.

Meanwhile, U.N. Secretary-General Antonio Guterres warned of the risk of any miscalculation amid global tensions “at their highest level this century.”

The U.N. chief says these tensions are “leading more and more countries to take unpredicted decisions with unpredictable consequences.”

Guterres told reporters Monday that his message is simple: “Stop escalation. Exercise maximum restraint. Re-start dialogue. Renew international cooperation,” and avoid a new war.
