"I myself have seen 15 people being swept away by water," Abdul Razzak, a resident of Pasni told Reuters by satellite phone. Pasni lies about 800 km (500 miles) south of provincial capital Quetta.

Provincial Minister Sher Jan Baluch, who also belongs to Pasni, said almost half of the town had been inundated.

"My own house has been swept away," he said but added that his family had moved to a safer place before flood came in.

He said death toll could rise.

Officials said flash floods also swept away several bridges on the main coastal highway linking Baluchistan to the southern port city of Karachi.

At least 31 people were killed by heavy elsewhere in the country over the past week.

Most of those who died were killed in avalanches, flash floods and collapsing roofs. Scores of others have been injured.

A family of eight, including six children, was killed when the roof of their mud house collapsed due to rain in Pishin area, about 40 km (25 miles) north of Quetta, according to local official Maqbool Anwar.

Another 13 people, including a soldier of the paramilitary Frontier Corps, were killed by flash floods or roof collapses in the southwestern province this week, officials said.

Remote northern areas, where the Himalaya, Karakorum and Hindu Kush mountain ranges collide, are cut off from the rest of the country, with roads buried under several feet of snow with the situation particularly bad in the Chitral valley.

"Around 2,700 families are desperately looking for food and blankets," said an official at the Relief Commissioner's office in the northwestern city of Peshawar.

The Karakorum Highway, linking Pakistan to China, has been blocked for two days and flights have been suspended since Feb. 3, said residents of Gilgit, the main town in the northern areas.

Six people were killed and four were injured in landslides in the Mansehra valley, 70 km (44 miles) north of Islamabad, on Wednesday, district commissioner officer, Hussain Zada Khan, told Reuters.

Another four people were killed in Pakistan-controlled Kashmir on Monday, three from avalanches in the southern Bagh district and another man from a roof collapse in Bhimber district, local officials said.

About 200 schools and colleges across the scenic Neelum valley in Kashmir were ordered to stay closed for a week due to the risky travelling conditions.

Weather officials said more rains were expected in the country for at least another two days.

"In the past four to five days we have been issuing warnings to the government departments that civil authorities should be prepared for emergency situations," Qamar uz-Zaman Chaudhry, head of Pakistan Meteorological Department, told Reuters.
