In flood-stricken Pakistan, restoration work is now underway at the ancient ruins of Mohenjo Daro, which were damaged by record rain.

The archaeological site in the southern Pakistani province of Sindh is believed to have been built about 4,500 years ago. It's ruins of an ancient city of brick structures representing the Indus civilization.

Mohenjo Daro is also designated as a UNESCO World Heritage Site.

Heavy rain since June has killed more than 1,600 people across Pakistan.

Damage from the disaster, such as collapses of brick walls, has been found at about 200 locations at the Mohenjo Daro site.

Local authorities launched repair work on Friday with archaeologists and officials checking damage and putting bricks back where they had been.

The authorities say restoring the site could take time as they are unable to get necessary materials in the wake of the flooding.

A local official said there could be more damage if rain starts again.
