Updated | 87 dead after crane collapses in Mecca

At least 87 people have been killed after a crane collapsed on to the Grand Mosque in the Saudi Arabian city of Mecca, the country's Civil Defence Authority has said.

The civil defence authority initially reported that some 30 people were wounded and 52 died.

BBC said it was not clear what happened, but images on social media showed a large number of dead and wounded.

The accident comes amid preparations for the annual Muslim Hajj pilgrimage to Mecca later this month.
