65 killed in crane collapse at Mecca mosque
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

Hundreds of thousands of people are expected to arrive in the Saudi city from all over the world later this month.
Reports suggested the crane fell on the east side of the mosque following high winds and rain. The Arabian peninsula has been has been hit by strong sand storms over the past week.
A video posted on YouTube, which could not be independently verified, appeared to record the moment the crane fell, with a loud crash heard in the background followed by panic and shouting.
Images circulating on Twitter appeared to show numerous bodies and blood on the floor of the mosque.
The mosque is Islam's most sacred site and the destination for millions of Muslims undertaking the Hajj pilgrimage every year.
Saudi authorities
began a major expansion of the site last year to increase the area of the mosque by 400,000 square metres (4.3 million square feet), to allow it to accommodate up to 2.2 million people at once.
More than three million people undertook the Hajj pilgrimage to Mecca in 2012. Saudi authorities have taken steps in 2013 to limit the number of people involved. Large numbers of people have resulted in several tragedies over the years, including a stampede in 2006 that killed nearly 350 people.
At the heart of the Grand Mosque is the Kaaba, a black cube-shaped building which Muslims all over the world face when they pray.
Islam requires that every Muslim capable of doing so performs a pilgrimage to the site at least once in their lifetime. Once at the mosque, pilgrims perform "tawaf" - walking seven times around the Kaaba in a counter-clockwise direction.
