The spokesman for Saudi Arabia's Interior Ministry says some 1,00,000 security personnel have been deployed to oversee the annual Islamic hajj pilgrimage that begins on Tuesday.
Maj Gen Mansour al-Turki says among those securing the massive crowds during hajj are members of an elite counter terrorism unit, traffic police and emergency civil defense personnel. They are being supported by additional troops from the army and national guard.
The pilgrimage comes as Saudi Arabia faces an expansion of Islamic State group attacks that have killed dozens of people this year. Al-Turki vowed on Saturday that militants "cannot control a centimeter anywhere in Saudi Arabia."
The hajj is expected to draw up to 3 million people from around the world this year to Mecca.
