At least 107 people were killed and another 239 were injured when a crane crashed in Mecca's Grand Mosque on Friday, Saudi Arabia's Civil Defense authority said on its Twitter account.
Pictures circulating on social media showed pilgrims in bloodied robes and masses of debris from a part of the crane that seemed to have crashed through a ceiling, NBC News reported.
Mecca is Islam's holiest site. Pilgrims from around the world have been converging on the city and the mosque for the annual Hajj pilgrimage, which takes place this month.
