Officials say the death toll from severe weather in northwestern Pakistan has risen to 45.

Mushtaq Ghani, the information minister for Khyber Pakhtunkhwa province, provided the latest toll Monday, saying several hundred people had been hospitalized.

The storm late Sunday brought heavy rains and winds of up to 120 kph (75 mph), causing hundreds of homes to collapse, uprooting trees and downing electric poles. Meteorological official Mohammad Hanif says the unusual storm caused tornadoes.

Ghani says thousands of people have been left homeless and crops have been washed away.

Pakistani army and civilian agencies have launched rescue and relief operations in the region.
