A rock mass collapsed at the Tarbela Dam in Pakistan, causing floodwater to surge into a tunnel and powerhouse. The incident occurred during excavation work at the second bench of the connecting tunnel at the Tarbela Fifth Extension Hydropower Project. Officials confirmed that all workers were evacuated safely.

The collapse happened in the northwestern Haripur area, where the dam is located. Waseem Ahmed, deputy commissioner of the region, stated that the weak section of the rock gave way during the operation. The water surge affected the tunnel and powerhouse, raising concerns about structural integrity. No casualties were reported, but the situation remains under close monitoring.

This is not the first incident at the Tarbela Dam. Previous reports have highlighted structural risks and maintenance challenges. The dam, a key infrastructure project, has faced issues related to aging infrastructure and environmental factors. The recent event underscores the ongoing risks associated with large-scale hydropower projects in the region. Authorities are conducting further assessments to ensure safety and prevent future incidents.
