A devastating flash flood in Swat on Friday swept away 19 people, including tourists, as torrential rains triggered a surge in the Swat River, leaving a trail of tragedy across the scenic valley.
According to officials, more than 80 people were trapped in different locations due to the sudden flooding. So far, 57 have been rescued, while bodies of at least 10 victims have been recovered.
Rescue operations are ongoing at five critical sites, with hopes fading for the missing as hours pass.
The most harrowing incident occurred in the Bypass Fizagat area, where 18 tourists drowned. Only three have been rescued alive, while eight bodies have now been retrieved. Seven individuals remain missing from that location, as confirmed by Rescue 1122. A woman’s body was the latest to be recovered from the Bypass site.
AFP adds: "In the past 24 hours, flash floods and landslides have claimed the lives of 11 people -- including four children and three women -- while six others have been injured," according to a report issued by the Khyber Pakhtunkhwa disaster management agency.
The report said 10 of those killed were in the Swat Valley, where, according to local media, a flash flood swept away families on a riverbank.
Flooding in the province has also damaged 56 houses, six of which were destroyed, the disaster agency report said.
The national meteorological service warned that the risk of heavy rain and possible flash floods will remain high until at least Tuesday.
Last month, at least 24 people were killed in severe storms in the country, which experienced several extreme weather events in the spring, including strong hailstorms.
Pakistan is one of the world's most vulnerable countries to the effects of climate change, and its 240 million inhabitants are facing extreme weather events with increasing frequency.
