Eight local volunteers were killed in a massive landslide while repairing the flood-damaged Danyor Nullah in Gilgit.
Several others sustained injuries and were rushed to nearby hospitals, where emergency services have been placed on high alert.
Rescue teams, assisted by local residents, are still searching for people believed to be trapped beneath the debris.
According to eyewitness accounts, the landslide struck suddenly as the volunteers were working to restore the damaged water channel.
Tonnes of earth and rocks buried multiple individuals, with police confirming that four people were pulled out alive but in critical condition.
