Flooding caused by heavy monsoon rains across much of Pakistan has killed nearly 1,000 people since mid-June, and thousands more have been injured and displaced, AP reported, citing officials.

The new death toll comes a day after Prime Minister Shahbaz Sharif asked for international help to fight deadly floods in the impoverished Islamic country.

The monsoon season, which began in June, has hit Pakistan with particularly heavy rains this year, and rescuers are struggling to evacuate thousands of people from flood-hit areas. The crisis forced the government to declare a state of emergency.

In the northwestern province of Khyber Pakhtunkhwa, flooding destroyed the gates of a major water control system in the Swat River, leading to flooding in the Charsadda and Nowshera districts.

In the Nowshera area, flood waters flooded the streets before the flood waters rushed into low-lying areas.

Information Minister Maryam Aurangzeb said soldiers and rescue organizations are helping people reach safety in many areas of southern Sindh, northwestern Khyber Pakhtunkhwa, eastern Punjab and southwestern Balochistan.

Aurangzeb asked wealthy people and relief organizations to come to the aid of flood-affected Pakistanis.

In response to Sharif's call for international assistance, the United Nations has planned a $160 million flash appeal for donations, according to Foreign Ministry spokesman Asim Iftikhar. He said at Friday's weekly briefing that the call would be launched on August 30th.

The National Disaster Management Authority said in its latest overnight report that 45 people died in the floods Friday through Saturday. As a result, the death toll since mid-June has reached 982 people, 1,456 were injured.

Monsoon rains are expected to continue this week, mainly in the south and southwest. Usually the season in Pakistan lasts from July to mid-September.

Torrential rains and subsequent flash floods damaged bridges, roads across Pakistan, disrupted the supply of fruits and vegetables to markets and caused prices to rise.
