Hundreds of thousands of people in Pakistan's northwestern Punjab province are fleeing their homes after the worst floods in the country's history destroyed many towns and villages, and killed more than 1,500 people.

UN and Pakistani officials say 3.2 million people are affected by the floods along the Indus River.

Camps have been set up to provide much needed food and medical aid for the flood victims.

But there are overwhelming signs of disease outbreaks, especially among women and children, due to a lack of clean drinking water.
