Saudi Arabia has begun an investigation after a crane collapsed in the Muslim holy city of Mecca, killing 107 people.

A massive construction crane crashes into Mecca's Grand Mosque in stormy weather Friday, killing 87 people and injuring 184, Saudi authorities say, less than a fortnight before the hajj pilgrimage starts.

Saudis are asking Snapchat to host this live coverage on the 27th day of Ramadan (13 July this year) as it is believed to be one of the more blessed nights of the month.
