Muslims participating in the Haj are praising safety measures that Saudi Arabia has put in place. Last year, 250 people were crushed to death during the stoning of the devil at Mena's Jamarat Bridge. This year, there haven't been any fatalities.
57,000 police and security forces have been placed in holy sites along with electronic signposts, an increase in the number of exits and other measures to insure crowd safety. Muslims are praising the measures for this once in a lifetime duty.
Large walls were erected to give the pilgrims a bigger target and avoid stampedes among Muslims trying to hit the walls. After pilgrims repeat the ritual three times, they cut their hair and go to Mecca to circle the Kabaa while wearing white robes.
