The CTD stressed that it is only assessing patterns in terror threats around the world so that Israelis can make informed travel plans, and not issuing formal travel advisories. The primary threats come from Iran, which the CTD called the main generator of global terrorism. Tehran continues its activities to promote harm to Israeli citizens and Jews around the world, it said. The report noted Iranian attempts to contact Israelis abroad in the guise of business or by impersonating others online. The CTD also stressed that Palestinian terror groups, most notably Hamas and Palestinian Islamic Jihad, have a high motivation to abduct Israeli nationals as bargaining chips.
