Islamabad: Up to four million children in Pakistan's flood-hit Sindh province are at risk of hunger and disease, an NGO said.

Only three percent of the USD357 million UN appeal have been received by Pakistan till date, the NGO Save the Children said.

About eight million people have been affected by the flooding this year in Sindh after torrential rains caused riverbanks to burst and overflow in late August.

Some villages were drowned, forcing people to flee to roadside, railway tracks, schools and higher ground in search of shelter.

The NGO started delivering food rations to 5,000 families in Sanghar district where 900,000 people have been affected, reports said on Friday.

Children and families are drinking from floodwater contaminated with sewage, the charity said.

Save the Children aims to provide support to one million people, including 600,000 children in four of the worst hit districts- Badin, Mirpurkhas, Sanghar and Tando Allahyar.
