At least 87 people were killed and more than 180 injured when a crane crashed through the ceiling of the Grand Mosque of Mecca amid high winds and thunderstorms today.
Dramatic footage shows the moment the crane toppled in heavy rain, with another video capturing the chaos and confusion inside the building as people run for cover after the impact.
Photos posted on social media shows the polished tiled floor of the mosque covered in rubble, bodies and pools of blood, and people fleeing the area bleeding and covered in soot.
