FILE - In this Tuesday, Oct. 23, 2012 file photo, Muslim Sunni and Shiite pilgrims pray outside the Grand Mosque in the holy city of Mecca, Saudi Arabia. There are distinctions in theology and religious practice between the two sects. Some are minor, like in prayer. Shiites pray with their hands by their sides, Sunnis with their hands crossed at their chest or stomach. Hatreds between Shiites and Sunnis are now more virulent than ever in the Arab world because of Syria's brutal civil war. Hard-line clerics and politicians on both sides have added fuel, depicting the fight as essentially a war of survival for their sect. (AP Photo/Hassan Ammar, File) less
