Monsoon rains in Pakistan could destroy UNESCO World Heritage Site

In flood-stricken Pakistan where an unprecedented monsoon season has killed hundreds of people, the rains now threaten a famed archeological site dating back 4,500 years, the site's chief official said Tuesday.

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 to this day, mystery surrounds the disappearance of its civilization, which coincided with those of ancient Egypt and Mesopotamia.

The swelling waters of the Indus, a major river in this part of the world, have wreaked havoc as heavy rains and massive flooding unleashed devastation across much of Pakistan. At least 1,325 people have been killed and millions have lost their homes in the surging waters, with many experts blaming the unusually heavy monsoon rains on climate change.

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.

Ancient drainage system may help protect site

He said dozens of construction workers under the supervision of archaeologists have started the repair work. Abbasi did not give an estimated cost of the damageat Mohenjo Daro.

Abbasi said the civilization at Mohenjo Daro, also known as "Mound of the Dead" in the local Sindhi language, built an elaborate drainage system, which has been critical during flooding in the past.

Though the floods have touched all of Pakistan, Sindh province has been among the worst hit.

Large lake may overflow

On Monday, army engineers made a second cut into an embankment at Lake Manacher, Pakistan's largest freshwater lake, to release rising waters in hopes of saving the nearby city of Sehwan from major flooding.

The water from the lake has already inundated dozens of nearby villages, forcing hundreds of families to leave their mud brick homes in a hurry, many fleeing in panic.

Meanwhile, rescue operations continued Tuesday with troops and volunteers using helicopters and boats to get those stranded out of the flooded areas and to the nearest relief camps. Tens of thousands of people are already living in such camps, and thousands more have taken shelter on roadsides on higher ground.

Ghulam Sabir, 52, from the outskirts of Sehwan, said Tuesday that he left his home three days ago after authorities told them to evacuate.

"I took my family members with me and came to this ... safer place," said Sabir, staying by the roadside where he has set up camp. He echoed complaints of several other villagers that no government help had reached them yet.

Sabir said he did not know whether his home had collapsed or not.

UNchief to visit Pakistan

Prime Minister Shahbaz Sharif urged Pakistanis in televised remarks Tuesday to generously donate to flood victims, most of whom are relying on government help to survive. Sharif has also repeatedly asked the international community to send more aid to the flood victims.

Last week, UNSecretary General Antonio Guterres also called on the world to stop "sleepwalking" through the crisis. He plans to visit flood-hit areas on Sept. 9.

According to Pakistani officials, Guterres will travel to Sindh but it's unclear whether he will visit the archaeological site.
