Machpela
In February 1994, Baruch Goldstein, a follower of the Kach party, murdered 29 Palestinians and wounded 125 at the Cave of the Patriarchs in Hebron, which became known as the Cave of the Patriarchs massacre. As an act of revenge to the massacre, in April 1994, Hamas launched suicide attacks targeting the Israeli civilian population in many locations throughout Israel, however, once the Hamas started to use these means it became a regular pattern of action against Israel.
