Impromptu settlement camps and sites set up for internally displaced people are overwhelmed as Islamabad and the United Nations struggle to respond.
"The monsoon rains may be over but the floods are not," said Andro Shilakadze, the head of the local office of UNICEF, in a statement.
There around 20 million Pakistanis affected by the flood, though more than 7.3 million are in Sindh province. More than 1 million homes were destroyed by flooding in the area and nearly 1.5 million people are forced to live in makeshift camps.
The U.N. Office for the Coordination of Humanitarian Affairs said more than 20,000 people are becoming displaced daily in Sindh province where the floodwaters continue to rise.
"We have not been able to scale up (the response) as quickly in the far south due to lack of funding," said Fawad Hussain, OCHA's relief coordinator for Sindh, in a statement.
