Americans warned against travel plans as terrorism threatens popular destination

The department recently reissued Israel's Level 3 advisory, "Reconsider Travel," though officials said there was no change to the overall advisory level.

The State Department warns that the security environment in Israel is complex and can change quickly.

Some areas carry the highest Level 4, "Do Not Travel," warning due to armed conflict.

Americans are advised not to travel to areas north of Route 85 to Route 90 south to Route 87, within seven miles of the Gaza Strip or within 1.5 miles of the Israel-Egypt border, except around the Taba border crossing.

U.S. government employees working in Israel are also restricted from traveling to those areas - and additional movement restrictions could be imposed "with little to no notice," due to increased security concerns or threats, according to the advisory.

For those Americans who decide to travel to Israel, officials recommend they stay aware of their surroundings, avoid demonstrations and crowds, and follow instructions from security and emergency officials.

Travelers are also advised to know the location of the nearest bomb shelter or other hardened shelter.

They should also have a plan to leave the country in an emergency that does not depend on U.S. government assistance, according to the advisory.

Fox News Digital reached out to the State Department for further details.

Fox News Digital previously reported that U.S. officials temporarily suspended government activities and travel to Mexicali, Mexico, last week after receiving information about a potential security threat.

The suspension has since been lifted and government activities have resumed.
