At least 87 dead in crane collapse at Mecca mosque
Accident occurs as pilgrims converge on Islam's holiest site for annual Hajj; videos and photos circulating on social media show grisly scene.
At least 87 people were killed and scores were wounded Friday when a crane collapsed in the Grand Mosque in Mecca, Saudi Arabia's civil defense authority said.
The accident happened as pilgrims from around the world converged on the city, Islam's holiest site, for the annual Hajj pilgrimage, which takes place this month.
The civil defense authority announced the collapse and a series of rising casualty numbers on its official Twitter account. It said 154 people were wounded in the accident.
Videos and photos posted by social media users showed a grisly scene, with police and onlookers attending to multiple bloodied bodies on the polished mosque floors.
Pan-satellite Al-Jazeera Television broadcast footage from inside the mosque compound said to be from the aftermath of the accident, showing the floor strewn with rubble and what appear to be pools of blood.
Another video, on a Twitter posting, captured the apparent moment of the crane's collapse during a heavy rainstorm, with a loud boom, screams and confusion.
Saudi authorities go to great lengths to prepare for the millions of Muslim who converge on Mecca to perform the sacred pilgrimage. Last year, it reduced the numbers permitted to perform haj for safety reasons because of construction work to enlarge the Grand Mosque.
The pilgrimage, one of the largest religious gatherings in the world, has been prone to disasters in the past, mainly from stampedes as pilgrims rushed to complete rituals and return home. Hundreds of pilgrims died in such a stampede in 2006.
Saudi authorities have since lavished vast sums to expand the main haj sites and improve Mecca's transportation system, in an effort to prevent more disasters.
Security services often ring Islam's sacred city with checkpoints and other measures to prevent people arriving for the pilgrimage without authorization.
Those procedures, aimed at reducing crowd pressure which can lead to stampedes, fires and other hazards, have been intensified in recent years as security threats grow throughout the Middle East.
