In the 1980s, Ben Shoshan and Yehuda Etzion, both members of the Gush Emunim Underground, plotted to blow up the al-Aqsa mosque and the Dome of the Rock. Etzion believed that blowing up the two mosques would cause a spiritual awakening in Israel, and would solve all the problems of the Jewish people. They also hoped the Third Temple of Jerusalem would be built on the location of the mosque. On 15 January 1988, during the First Intifada, Israeli troops fired rubber bullets and tear gas at protesters outside the mosque, wounding 40 worshipers. On 8 October 1990, 22 Palestinians were killed and over 100 others injured by Israeli Border Police during protests that were triggered by the announcement of the Temple Mount Faithful, a group of religious Jews, that they were going to lay the cornerstone of the Third Temple.
