Juhayman al-Otaybi and his followers, members of the Otaibah tribe who called themselves al-Ikhwan, opposed the Saudi monarchy's alliances with Western nations and its perceived drift toward secularism. They also proclaimed fellow militant Muhammad Abdullah al-Qahtani to be the Mahdi, providing religious justification for their planned uprising against the House of Saud.
On 20 November 1979, up to 600 militants seized the Grand Mosque in Mecca, taking worshippers hostage and calling for rebellion against Saudi rule. Saudi forces, aided by French GIGN advisors who supplied specialized tear gas, mounted a counteroffensive. After two weeks of fighting, the mosque was retaken. Al-Qahtani was killed in the operation, while Juhayman and 67 other militants were captured, tried, and publicly executed by beheading.
The seizure, coinciding with the Iranian Revolution, inflamed tensions across the Muslim world. Iranian cleric Khomeini's false accusation that the United States and Israel had orchestrated the attack sparked large-scale anti-American riots in multiple Muslim-majority countries. Within Saudi Arabia, King Khalid responded by strengthening Islamic law, granting the ulama expanded authority, and empowering the religious police to enforce stricter social codes.
