Israeli physician Baruch Goldstein opened fire on Palestinian Muslims praying at the mosque in Hebron's Cave of the Patriarchs, killing 29 people and wounding 125 others.

Baruch Goldstein
Baruch Kopel Goldstein was an American and Israeli physician and religious extremist who, in 1994, murdered 29 Palestinian people in Hebron in the Israeli-occupied West Bank, an incident of Jewish terrorism. Goldstein was a supporter of Kach, a religious Zionist party that the United States, the European Union and other countries designate as a terrorist organization. Kach was banned less than a month after Goldstein's attacks on account of statements made in support of his actions.
Cave of the Patriarchs massacre
On 25 February 1994, Baruch Goldstein, an American-Israeli physician and extremist of the far-right ultra-Zionist Kach movement, carried out a mass shooting of Palestinians who were praying in the Ibrahimi Mosque in Hebron. Goldstein, dressed in Israeli army uniform, opened fire with an assault rifle and killed 29 people, including children as young as 12, and wounded 125 others. Goldstein was overpowered and beaten to death by survivors.
Hebron
Hebron is a city in the southern West Bank, Palestine and capital of the Hebron Governorate, which is the largest in the West Bank. It is located 30 kilometres (19 mi) south of Jerusalem. The population inside in the city limits is 201,063, while the adjacent metropolitan area within the governorate is home to over 700,000 people. Hebron spans across an area of 74.1 square kilometres (28.6 sq mi). It is the third largest city in the country after Gaza and East Jerusalem. The city is often considered one of the Four Holy Cities in Judaism, as well as in Christianity and Islam.
Cave of the Patriarchs
The Cave of the Patriarchs or Tomb of the Patriarchs, known to Jews by its Biblical name Cave of Machpelah and to Muslims as the Sanctuary of Abraham, is a series of caves situated in the heart of the Old City of Hebron in the West Bank, 30 kilometres (19 mi) south of Jerusalem. According to the Abrahamic religions, the cave and adjoining field were purchased by Abraham as a burial plot, although most historians believe the Abraham-Isaac-Jacob narrative to be primarily mythological. The site is considered a holy place in Judaism, Christianity, and Islam.
