Saudi Arabian King Salman has promised to investigate the cause of a crane collapse at the Grand Mosque of Mecca. The collapse left 107 people dead.
"We will investigate all the reasons and afterwards declare the results to the citizens," said King Salman.
The annual Hajj pilgrimage will begin soon and hundreds of thousands of visitors have already arrived in Saudi Arabia. Many pilgrims felt no need to mourn, and instead took touristy pictures of the wreckage.
