MOUNT ARAFAT: Some two million Muslims from around the world began gathering Thursday on Mount Arafat for the highlight of the Hajj pilgrimage to Saudi Arabia dedicated to prayers and reflection.

The second day of the Hajj, a must for all able-bodied Muslims who can afford it, is dedicated to prayer and reflection.

Arafat is the site where Prophet Muhammad (PBUH) gave his last sermon about 14 centuries ago after leading his followers on the pilgrimage.

In the evening, the pilgrims will travel to Muzdalifa where they will stay the night before taking part in a symbolic stoning of the devil.

At the foot of Mount Arafat, mobile barriers have been installed to control the movement of the crowds.

"They will be moved to enlarge the passages when there are more pilgrims," said Ahmed al-Baraka of the Saudi security forces.

The kingdom has deployed more than 100,000 security personnel to keep pilgrims safe at this year´s Hajj, according to the interior ministry.

According to Arab news, thousands of security men accompanied the pilgrims along Mina's wide roads, bridges and tunnels.

Their journey went smoothly despite the huge number of vehicles and pedestrians.

Traffic patrols were assisted by security forces in their efforts to organise the traffic, guide pilgrims and maintain security.

The Ministry of Health is offering medical and health care services to pilgrims during this year's Hajj season by providing thousands of doctors, nurses and specialists appointed to serve pilgrims.

These members work at hospitals near the holy sites and Makkah.

The ministry assists the relevant authorities in carrying out the general emergency plan and dealing with emergencies that might arise during the pilgrims' stop in Mina and Jamaarat bridge.

Along with the ministry, medical service departments of the National Guard Ministry, and Defense Ministry and its hospitals appointed hundreds of their members to offer medical and treatment services to pilgrims at the holy sites.

The Saudi Red Crescent Authority (SRCA) is providing its services through thousands of members appointed to serve Hajjis.

The organisation designated a fleet of 100 ambulances spread throughout the holy sites.

The Hajj and Umrah pilgrimages bring millions of Muslims to the holy places in Saudi Arabia every year.
