Pakistan’s monsoon rains threaten world heritage site of Mohenjo-daro

Curator of site says several walls built 4,500 years ago have collapsed and repairs are under way

In flood-stricken Pakistan, where an unprecedented monsoon season has killed hundreds of people, the rains now threaten a famed archaeological site dating back 4,500 years.

The ruins of Mohenjo-daro, located in southern Sindh province near the Indus River, and a Unesco world heritage site, are considered among the best preserved urban settlements in south Asia. They were discovered in 1922, and mystery still surrounds the disappearance of its civilisation, which coincided with those of ancient Egypt and Mesopotamia.
