The Ma’alot massacre[1] was an attack on May 15, 1974 in Ma’alot, Israel, in which 22 Israeli high school students, aged 14–16, from Safed were killed by three members of the Democratic Front for the Liberation of Palestine.[2] Before reaching the school, the trio shot and killed two Arab women, a Jewish man, his pregnant wife, and their 4 year old son, and wounded several others.[3] http://en.wikipedia.org/wiki/Ma%27alot_massacre
