A tragic incident occurred on July 3, 1990, when a deadly stampede happened in a pedestrian tunnel leading from Mecca towards Mina and the Plains of Arafat in Saudi Arabia. The disaster resulted in the deaths of approximately 1,400 pilgrims who were participating in the annual Hajj pilgrimage. This incident remains one of the deadliest Hajj-related tragedies in history. It prompted significant improvements in crowd control and safety measures by Saudi authorities to prevent such tragedies in the future, reflecting the challenges of managing one of the largest religious gatherings in the world.
