Several hundred thousand more people have fled towns and villages threatened by fresh flooding in Pakistan's southern province of Sindh.
Water is gushing towards Dadu district because of a breach in the Toori dam at upper Sindh.
In the past weeks all but four of Sindh's 23 districts have been deluged.
Aid agencies say more than eight million people who have left their homes need food and water.
Most of the floodwaters are pouring down from the Toori dam, which was washed away in August.
The breach has caused the waters of the River Indus to split in two.
One side is continuing to flow to the Arabian sea, while the other is going parallel to the Indus's natural course, wreaking a path of destruction.
This rogue flow of water has now reached Dadu district, and is pouring into Manchar, the country's largest freshwater lake.
