Saudi Arabia ? The Saudi health minister said Saturday that the kingdom will not bar anyone considered high-risk for swine flu from performing the hajj pilgrimage this year, though he urged countries where pilgrims set out from to take precautions.

The hajj, required of all able-bodied Muslims at least once in their lifetime, has become a concern for world health officials because the density of pilgrims — with shoulder-to-shoulder contact as they pray — has raised fears of a massive spread of swine flu.

The pilgrimage attracts about 3 million people from 160 countries annually.
