A huge construction crane -- buffeted by strong winds -- collapsed and crashed through the roof of the Grand Mosque in Mecca, Saudi Arabia today (September 11, 2015), killing at least 62 worshipers in the city for the annual Muslim pilgrimage, the USA Today website reports.
Photos sent by Twitter from the scene show numerous blood-covered bodies strewn on a marble floor. The arm of a huge crane appears through a large hole in the roof of the mosque. Even before the crane accident, the Civil Defense was warning of thunderstorms, heavy rain and wind in the area.
The Grand Mosque -- or Great Mosque as it is also called -- is the largest mosque in the world. It surrounds Islam's holiest place, the Kaaba, in the city of Mecca, where the Islamic prophet Mohammad was born.
One of the five pillars of Islam requires all Muslims to perform the Haji pilgrimage at least once in their lifetime. The Haji is one of the largest annual gatherings of people in the world.
