The discovery was made after the protective wall of a Stupa fell down during the torrential rainfall that the province of Sindh experienced; however no water was seen accumulated at the site, according to a report by the BBC.
Manzoor said that his team had nothing to do with the lack of water accumulation in Mohenjo-Daro, telling the BBC that when they rushed to the site, they were surprised that the water had drained out from the ancient city through the 4,500-year-old drainage system.
The drained water then poured out into a compound that was built a few years ago, and it took Ahmed's team three weeks to drain it out of there.
The remains of the ancient civilization at Mohenjo-Daro have been given a special status by United Nations Educational, Scientific and Cultural Organization (UNESCO), and are part of the UNESCO World Heritage Sites.
Earlier in August, reports surfaced that UNESCO had revoked the special status given to Mohenjo-Daro; however, those reports have been proven to be false. According to Manzoor Ahmed, UNESCO cannot take such a big decision without first consulting Pakistan.
"Experts have only warned that if the site's maintenance is not carried out as per UNESCO's recommendations, it could be delisted," he said, explaining that no where was it said that it has been removed from the list.
