Israeli facilities in North America — and around the world — are on high alert, according to an internal security document obtained by ABC News that predicted the threat from Iran against Jewish targets will increase.

“We predict that the threat on our sites around the world will increase … on both our guarded sites and ‘soft’ sites,” stated a letter circulated by the head of security for the Consul General for the Mid-Atlantic States. Guarded sites refers to government facilities like embassies and consulates, while ‘soft sites’ means Jewish synagogues, and schools, as well as community centers like the one hit by a terrorist bombing in Buenos Aires in 1994 that killed 85 people.

The head of Shin Bet, Israel’s internal security service, told an audience at a closed forum in Tel Aviv recently that Iran is trying to hit Israeli targets because of what it believes are Israeli attacks on it nuclear scientists. Yoram Cohen said that Iran’s Revolutionary Guard, the same militant wing of the government linked to the recent alleged plot against the Saudi ambassador to the U.S., is working tirelessly to attack Israeli and Jewish targets abroad in order to deter Israel.

Local and regional law enforcement and intelligence officials in U.S. and Canadian cities, including New York, Los Angeles, Philadelphia, and Toronto have been monitoring the situation closely for several weeks, and have stepped up patrols at Israeli government locations and Jewish cultural and religious institutions. They have issued awareness bulletins reminding officers to stay vigilant.

Federal officials in those cities told ABC News that they have also increased their efforts to watch for any threat stream pointing to an imminent attack on either Israeli facilities, Jewish cultural or religious institutions or other “soft targets.”
