The crane crashed into the Grand Mosque as it was full of worshippers, almost two weeks before the Hajj pilgrimage. <br /> <br />Officials say strong winds and heavy rains caused the crane to fall. <br /> <br />Correspondents say there had previously been concerns about safety on Saudi construction sites. <br /> <br />King Salman visited the site late on Saturday, and then met survivors of the accident in hospital. <br /> <br />"We will investigate all the reasons [of the collapse] and afterwards declare the results to the citizens," the official Saudi news agency quoted him as saying. <br /> <br />The victims were said to include worshippers from Iran, Turkey, Afghanistan, Egypt and Pakistan.
