Mina, Sep 1: Amidst tight security, over two million Haj pilgrims from around the world participated in the ritual of stoning of the Jamarat -- huge pillars of stones symbolising Satan -- in the Saudi holy city of Mina on Friday. The pilgrims came back to Mina from Muzdalifah early in the morning to perform main rituals of Haj on Friday, which coincided with the beginning of the celebration of Eid Al-Adha by Muslims all over the world, the Saudi Gazette reported. Custodian of the Two Holy Mosques King Salman arrived in Mina on Thursday night to oversee the Kingdom's Haj preparations. He received several princes, Grand Mufti Sheikh Abdul Aziz Al-Asheikh and other scholars and commanders of the security forces taking part in Haj at Mina Palace on Friday. Hundreds of thousands of the faithful attended Eid prayers at the Grand Mosque in Makkah and the Prophet's Mosque in Madina. According to the latest reports by the General Authority for Statistics, as many as 2,352,122 pilgrims performed the Haj this year - comprising of 1,752,014 Hajis who came from outside and 600,108 domestic pilgrims, the newspaper reported. The Civilian Protection teams of the Kingdom were on alert and ready to deal with any emergency situation and undertaking any evacuation, shelter, or relief operations, an official said.

These teams are also supported by Civil Defense teams that have been distributed all over the Holy Sites," Col. Dhafir Al-Asmari explained. Tunnels and pedestrian walkways are being closely monitored by advanced technology devices.
