(CNN)A crane collapsed Friday at one of Islam's most important mosques -- the Masjid al-Haram in Mecca -- killing at least 65 people and injuring 154 others, Saudi Arabian authorities said Friday on Twitter.
There was no immediate comment about the cause of the collapse.
The Masjid al-Haram surrounds Islam's holiest site, the Kaaba -- a shrine that worshipers visit during the Hajj, the annual pilgrimage to Mecca. Approximately 2 million people a year make the pilgrimage.
The Hajj is due to begin later this month.
