MAKKAH: Hundreds of thousands of Muslims from across the globe began the annual Hajj pilgrimage on Tuesday in one of the largest annual gatherings of people in the world.
In what for many will be the highlight of their spiritual lives, pilgrims began moving from holy city of Makkah to nearby Mina for the start of the six-day event.
Almost two million people are expected to take part in this years pilgrimage, undeterred by a crane collapse at Makkahs Grand Mosque earlier this month that killed 109 people and injured nearly 400 at Islams holiest site.
Joyous pilgrims like 35-year-old Egyptian Walaa Ali had been gathering for days ahead of the event.
It is a gift from God that He has chosen us to come here, Ali said with tears in her eyes, as preachers nearby explained the history and rituals of the Hajj to men and women sitting side by side in Makkah.
I am so happy to be here, she said.
This years Hajj takes place against a backdrop of increased extremist violence in some Muslim countries, a surge of the potentially deadly MERS virus and the war in neighbouring Yemen.
The hajj is among the five pillars of Islam and every capable Muslim must perform the pilgrimage at least once in his or her life.
But preparations for this years event were marred when a construction crane working on an expansion of the Grand Mosque collapsed during severe winds.
Saudis, Iranians, Nigerians, Malaysians, Indonesians and Indians were among the dead.
About 100,000 police have been deployed to secure pilgrimage sites and manage the crowds, and authorities say they are on alert for possible attacks by extremists.
The extremist Daish group also known as ISIS has carried out bombings targeting security forces and Shia mosques in the kingdom in recent months.
Security forces have taken measures to prevent terrorist groups from exploiting Hajj season to carry out acts of sabotage, interior ministry spokesman General Mansur al-Turki said.
We take all possibilities into consideration during Hajj. This includes the kingdom being targeted by terrorist organisations, he told AFP.
This years Hajj also comes with Saudi Arabia at war, leading an Arab coalition conducting air strikes in Yemen.
Most Yemeni complain they have been denied Hajj visas this year for fear of anti-Saudi protests in the holy cities.
Around five thousand people, mostly civilians, have been killed in Saudi air strikes that began in March.
Among other challenges facing Saudi authorities is potential transmission of the deadly Middle East Respiratory Syndrome coronavirus (MERS-CoV).
The capital Riyadh saw a jump in infections last month, but health officials say there has never been a case of MERS infection among pilgrims.
Saudi Arabia is the country worst affected by MERS, with 532 deaths since the virus appeared in 2012.
The health ministry has mobilised thousands of health workers to help secure a virus-free pilgrimage and to care for routine ailments.
The first day of the Hajj is known as Tarwiah Day, when pilgrims traditionally watered their animals and stocked water for their trip to Mount Arafat, about 10 kilometres southeast of Mina.
Pilgrims stay in specially-built fireproof tents in Mina, a city which only comes alive during Hajj season.
At Mount Arafat they will pray and recite from the Quran during the climax of the Hajj season on Wednesday.
Mount Arafat, a rocky hill on a vast plain, is where the Prophet Muhammed (pbuh) is believed to have given his final sermon after leading his followers on the Hajj.
With the start of the Hajj, pilgrims enter ihram, a state of purity in which they must not quarrel, wear perfume, cut their nails, or trim their hair or beards.
During ihram, men wear a seamless two-piece shroud-like white garment, symbolising resurrection and emphasising unity regardless of social status or nationality.
Women must wear loose dresses, generally also white, exposing only their faces and hands. Agencies
