The Ma'alot massacre was a Palestinian terrorist attack that occurred in May 1974 and involved a two-day hostage-taking of 115 Israelis, which ended in the murders of 25 hostages and six other civilians. It began when three armed members of the Democratic Front for the Liberation of Palestine (DFLP) entered Israel from Lebanon. Soon afterwards they attacked a van, killing two Israeli Arab women while injuring a third and entered an apartment building in the town of Ma'alot, where they killed a couple and their four-year-old son. From there, they headed for the Netiv Meir Elementary School, where they took more than 115 people (including 105 children) hostage on 15 May 1974, in Ma'alot. Most of the hostages were teenagers from a high school in Safad on a Gadna field trip spending the night in Ma'alot. The hostage-takers soon issued demands for the release of 23 Palestinian militants from Israeli prisons, or else they would kill the students. On the second day of the standoff, the Sayeret Matkal stormed the building. During the takeover, the hostage-takers killed children with grenades and automatic weapons. Ultimately, 25 hostages, including 22 children, were killed and 68 more were injured.
