In the time since my last post I read the book "Siege of Mecca" wherein a hundred or more armed Sunni Jihadis siezed the shrine at Mecca in 1979 and proclaimed one among them the 'Mahdi'. They were rooted out after two weeks of battle with various armed forces. The Saudis finally evicted them with poison gas, and took over 68 prisoners. They were distributed among the cities of Saudi Arabia and beheaded via swords.
