The office of Israel’s Prime Minister Netanyahu has called on citizens traveling abroad to heighten their awareness in light of the terrorist threat posed by ISIS.

The message to the public, posted recently by the PMO’s National Security Council, encourages Israelis to avoid or remain extra cautious in crowded areas, especially over the holiday season.

While it said there was no “concrete information” about any specific attack, the notice indicated a marked increase in terrorism since November, both in scale and scope, by global jihadi groups like ISIS.

Among the areas singled out for increased caution were “tourist attractions, sports stadiums, cultural sites, shopping and recreation centers, hotels, airports and public transportation hubs.”

The message also encouraged travelers to remain up-to-date with local news and to listen for comments by security officials.
