"Four pilgrims have died of swine flu as they take part in this year's annual Mecca pilgrimage, Saudi officials say.
Three of the victims - a woman from Morocco and men from Sudan and India - were in their seventies. The fourth was a 17-year-old girl from Nigeria.
The Health Ministry said none of the four foreign victims had been vaccinated against the H1N1 virus.
