Pakistan's Monsoon Rains Threaten 4,500-Year-Old UNESCO World Heritage Site

Mystery still surrounds the disappearance of the civilisation in this 4,500 year old city, which coincided with those of ancient Egypt and Mesopotamia

Pakistan’s catastrophic floods are threatening one of the world’s oldest known cities after the large-scale devastation already led to the death of over 1,300 people and destroyed billions of dollar worth of property.

The authorities in the southern Sindh province have said the flooding poses an imminent risk to the ruins of Mohenjo Daro — a 4,500-year-old city of the ancient Indus Valley civilisation and a UNESCO world heritage site.

The flooding has not directly hit Mohenjo Daro, but the record-breaking rains have inflicted damage on the ruins of the ancient city, said Ahsan Abbasi, the site’s curator.

“Several big walls, which were built nearly 5,000 years ago, have collapsed because of the monsoon rains,” Abbasi told The Associated Press on Tuesday.

He said dozens of construction workers under the supervision of archaeologists have started the repair work. Mr Abbasi did not give an estimated cost of the damages at Mohenjo Daro but Pakistan’s government has said the overall damages from the flood may be over $13bn now.
