At least 87 people are dead after a construction crane crashed into the Grand Mosque in Mecca, Islam’s holiest city.
Al Arabiya, the Saudi-owned broadcaster, also said 184 people were wounded. It cited the Saudi Civil Defense authority.
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.
The incident occurred as hundreds of thousands of Muslims are due to gather from around the world for the annual hajj pilgrimage set to begin later this month.
Search-and-rescue teams are on the scene, and are transporting the injured to hospital, Al Arabiya reported. Prince Khalid al-Faisal, the governor of Mecca Province, has ordered an investigation into the collapse, the state-run Saudi Press Agency reported.
