Several people were killed and others injured when storms caused a crane to fall on Saudi Arabia's Grand Mosque in Mecca on Friday, Saudi-owned Al Arabiya television reported.
At least 65 people were killed when a crane crashed in Mecca's Grand Mosque on Friday, Saudi Arabia's Civil Defence authority said, in an accident that came just weeks before Islam's annual haj pilgrimage.
The civil defence said on its Twitter account 154 people were also injured in the accident. Al Arabiya television earlier said the crane had fallen because of strong storms - western Saudi Arabia has been hit by strong sand storms in the last few days. Pictures circulating on social media showed pilgrims in bloodied robes and masses of debris from a part of the crane that seemed to have crashed through a ceiling.
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.
