Of the total rain-related casualties, 31 deaths were reported in southern Sindh province, while 23 people died in the province of Khyber Pakhtunkhwa, according to the agency. It said 15 deaths were reported in southwestern Baluchistan province and eight in Punjab province. Thirteen more people died elsewhere in northern Pakistan, including three in the Pakistan-administered sector of Kashmir.
Troops, rescuers and volunteers from the radical Islamist group Tehreek-e-Labbaik were seen evacuating people from inundated residential neighbourhoods in Karachi as some families waded through waist-high water. Hundreds of rain-affected people went to the houses of relatives in the country's largest city.
According to the National Disaster Management Authority, troops using boats evacuated 300 people from rain-hit district of Dadu in Sindh province, while 1245 people were evacuated from Karachi's rain-hit areas, where residents said they were still waiting for help.

The rains are expected to continue this week in Karachi, where Prime Minister Imran Khan earlier this month sent troops to help local authorities in pumping out rainwater from inundated residential areas.
