"Five million people have been affected by floods in the Pakistani provinces of Baluchistan and Sindh, according to regional officials.
At least 133 people have been killed, officials said, and the number is expected to rise.
About 900 villages have been submerged and about 100,000 homes have been completely destroyed.
"People are moving whatever little they can because of the rising waters," Al Jazeera's Kamal Hyder, reporting from Badin, one of the worst-hit districts in Sindh province, said on Friday. "The water has been rising in the last few weeks because of heavy rain.
He said residents in the area were in desperate need of assistance, asking for food, drinking water and shelter."
