Egyptian Muslim pilgrims pray after they cast stones at a pillar, symbolizing the stoning of Satan, in a ritual called "Jamarat," the last rite of the annual hajj, in Mina near the Muslim holy city of Mecca, Saudi Arabia, Thursday, Oct. 17, 2013. This year some pilgrims and security personnel are wearing masks as a precaution against the Middle East respiratory syndrome, which has stricken nearly 100 people, most of them in Saudi Arabia and the Middle East.Amr Nabil/The Associated Press
