SAUDI ARABIA:The annual haj pilgrimage began in Mecca yesterday when hundreds of thousands of Muslim pilgrims put on white clothes, packed their bags and left for a tented encampment on the edge of the holy city.
In central Mecca, some latecomers performed the ritual walk seven times around the Kaaba, the ancient cubic shrine which all Muslims face when they perform their daily prayers.
More than 1.6 million pilgrims have come to Saudi Arabia from abroad for the haj, the largest regular religious gathering in the world and an obligation which all Muslims should perform at least once if they are able to.
Pilgrims from within Saudi Arabia - Saudis or foreign workers - mean the total often exceeds 2.5 million, posing logistical and health challenges for the authorities.
"We have to raise [ health] awareness among pilgrims from some countries," health minister Hamad al-Manei told al-Jazeera, the Arabic broadcaster, which has been permitted to cover the rites this year.
"Some of the pilgrims coming from outside do not know Arabic. With different languages and peoples coming, of course there are difficulties," the minister said from Mecca.
The government has said it will crack down on pilgrim squatters who cause overcrowding and has taken precautions against bird flu - recently the deadly H5N1 strain of the virus killed birds in Riyadh.
By the evening the pilgrims should all have reached the Mina area east of Mecca, the first overnight stage in an itinerary which will bring them back to Mecca later this week.
Some of them walked, carrying their bags, while others took buses moving slowly through the crowds.
Pilgrims see the haj as an affirmation of Muslim unity and solidarity, bringing together people of different languages and ethnicities united only by belief in a single god.
On a personal level, many of them say they are also seeking forgiveness for sins of which they have repented.
"A good haji (pilgrim) will go home like a new-born child. All his sins are forgotten," said Nigerian sociology professor Baffa Aliyu Umar, who is on his fourth haj.
