Some 2,000 Shia pilgrims gathered near the mosque that houses the Prophet’s tomb for the commemoration of Mohamed’s death, an act of worship that the ruling Saudi Wahhabi sect considers heretical and idolatrous. Thus, the Mutawa’ah, the religious police of the Committee for the Preservation of Virtue and the Prohibition of Vice, armed with sticks and backed by police firing into the air, tried to disperse the pilgrims.
