Over 65 people were killed after a crane collapsed on to the Grand Mosque in the Saudi Arabia's holy city of Makkah, which is preparing for the Annual Haj.
At least 65 people have been killed and at least 30 injured, reported the BBC, citing the Saudi civil defence authority.
It was raining heavily at the time. Few other details are available. Images from the scene showed part of a huge red crane had crashed through the roof of the mosque.Mecca is preparing for the annual Muslim Hajj pilgrimage.
Construction work has been going on at the Grand Mosque for years to make it big enough to cope with the huge numbers of people who come each year.
The incident occurred as hundreds of thousands of Muslims gather from all over the world for the annual hajj pilgrimage set to begin later this month, and Saudi authorities go to great lengths to be prepared for the millions of Muslims who converge on Makkah.
The Grand Mosque is usually at its most crowded on Fridays, the Muslim weekly day of prayer.
Last year, the kingdom reduced the numbers permitted to perform haj for safety reasons because of construction work to enlarge the Grand Mosque.
