Islamabad, Pakistan (CNN) -- The death toll from flooding in Pakistan has risen to at least 800, the information minister of a northern province said Saturday.
The death toll only affects Khyber Pakhtunkhwa province, previously known as the North West Frontier Province, said spokesman Mian Iftikhar Hussain.
Flooding has also been reported in Pakistani-controlled Kashmir. Twenty-five deaths were recorded there Friday, Hussain said.
Many of the victims died when floodwaters swept away hundreds of mud houses in parts of Swat Valley and the districts of Shangla and Tank, according to Bashir Ahmed Bilour, a provincial minister in Khyber Pakhtunkhwa.
Rushing water also has washed away thousands of acres of crops and dozens of government buildings, local businesses and schools, Bilour said.
Hussain said floodwater has cut off the Swat Valley and the districts of Shangla and Peshawar. There is no way to get to these areas by road, he said.
The Pakistani Air Force has been helping with rescue efforts, spokesman Tariq Yazdanie said in an interview on Pakistani TV. The recent torrential rains have broken all previous records of rainfall in the country, he said.
