On Tuesday, two Palestinian terrorists entered a synagogue in Jerusalem and killed four people during morning prayers, then killed an Israeli police officer responding to the scene. This attack is the latest in a recent string of heinous attacks by Palestinian terrorists.

Three other recent victims were U.S. citizens. The American victims include both Naftali Frankel, a student who was abducted and murdered while hitchhiking home from school, and Chaya Zissel Braun, a 3-month-old baby murdered by a terrorist who used his car as a weapon.
