Rescue teams were looking for possible survivors from the downpours that caused heavy flooding in the coastal city of Jiddah, the main entry point for the millions of Muslims performing the annual hajj pilgrimage.

The official spoke to The Associated Press on Saturday on condition of anonymity because he is not authorized to talk to the media.

The deaths have been blamed on flooding and collapsed homes and bridges in the port city.

Sami Badawood, a health services spokesman in Jiddah, said in a statement that area hospitals have been equipped to deal with any possible outbreaks of diseases resulting from the flooding, such as dengue fever.

Rare, heavy rainstorms soaked pilgrims and flooded the road into Mecca, snarling Islam's annual hajj as millions of Muslims headed for the holy sites. However, none of the flood casualties were pilgrims, officials said.
