ISLAMABAD, Feb. 22 (Xinhua) -- At least 28 people were killed and over two dozen others injured in the latest wave of extreme weather across Pakistan, local media and officials have said.

According to the reports, the death took place due to torrential rains, thunderstorms and heavy snowfall that started earlier this week in different areas of the country.

Chief Minister of the country's southwest Balochistan province Jam Kamal Khan told media Thursday that at least four people were killed in flash floods caused by the torrential rains in the province.

Over 450 families have been affected by weather-related incidents across Balochistan, said the chief minister, adding that an emergency has been declared in Lasbela district where some 200 families were affected by the flash floods which submerged nearby villages.

Rescue workers along with four helicopters are busy in rescue and relief operations in the flooding areas, the chief minister said.

The chief minister added that the floods have damaged communication infrastructure as heavy rainfall played havoc across the province.

At least 14 people were killed in the landslide, roof collapse and snowfall related incidents in northwest Khyber Pakhtunkhwa province, the reports said.

The country's eastern Punjab province also suffered heavy rains where at least nine people, including a family of four, lost their lives when the roofs of their houses caved in after heavy rains.

A child died in a rain-related accident in Pakistan-controlled Kashmir region.
