Tragedy has just struck one of Islam’s most significant religious sites. According to reports, at least 65 people are dead and more than 150 have been injured after a construction crane collapsed on top of the Masjid al-Haram mosque at Mecca. The area attracts millions of Muslims each year, especially during the Hajj pilgrimage which starts next month. Masjid al-Haram is the largest mosque in the world.
