And eleven days ago

A bomb found near the Tomb of the Patriarchs and Matriarchs in Hebron was detonated by police on Sunday. Border police stationed outside of the ancient historic and religious site noticed the suspicious device and scrambled sappers to the area, clearing it of all civilians. The device, which included two small gas canisters, was blown up by the police bomb squad in a controlled explosion, near one of the entrances typically used by Muslims. Police launched an investigation, and issued a statement in which they promised to “protect the security of all the citizens, residents and visitors” to the Judea burial place of biblical forbears Abraham, Sarah, Isaac, Rebecca, Jacob and Leah.
According to local law enforcement, “in the area of the tomb, there is unique coexistence that the security forces, including border police, protect with the goal of allowing freedom of worship and religion to both Jews and Muslims at the Tomb of the Patriarchs.” ["Bomb near Tomb of the Patriarchs detonated by police", Jewish News Syndicate, June 11, 2018]

The Cave of Machpelah - part of the Tomb of the Patriarchs complex, is "the world's most ancient Jewish site and the second holiest place for the Jewish people, after Temple Mount in Jerusalem... Over 300,000 people visit Ma'arat HaMachpelah annually. The structure is divided into three rooms: Ohel Avraham, Ohel Yitzhak, and Ohel Ya'akov. Presently Jews have no access to Ohel Yitzhak, the largest room, with the exception of 10 days a year." [Jewish Virtual Library]
