Heavy rainstorms soaked pilgrims and flooded the road into Macca, snarling Islam's annual hajj as millions of Muslims headed for the holy sites. The downpours add an extra hazard on top of intense concerns about the spread of swine flu. Pilgrims in white robes holding umbrellas, some wearing face masks for fear of the flu, circled Kaaba in Macca, the opening rite for the hajj. But the shrine Islam's holiest site and the nearby, rain-soaked streets did not see the usual massive crowds, because many tried to stay inside nearby hotels or were caught up in the traffic jams heading into the city.
