The mud flow descended into the main Ghizer River channel and blocked it completely on Friday, creating the lake in Gilgit Baltistan province, the National Disaster Management Authority said.

A 7-km (4-mile) lake in northern Pakistan, created by a mountain mudslide, is threatening to burst and unleash potentially "catastrophic" floods downstream, officials warned on Saturday.
