Engineers are at the site of the Tarbela Dam, north west of Islamabad as the huge structure threatens to collapse. Latest reports say that two of the four huge tunnels under the dam have been ripped apart from the inside and the concrete bed has partly collapsed. The dam holds back nearly nine and a half million acre feet of water and it's been decided to let this water free in the hope it will prevent a complete collapse of the dam. But the water has to be released gradually to prevent flooding.
The Tarbela is the largest earth filled dam in the world. It was built by a foreign consortium of 13 construction firms from Italy, France, Switzerland and Germany. There was one report that a representative of the American consultants had committed suicide early last month after allegedly confessing he had made a designing mistake.
The reason for the collapse still isn't known and an official inquiry will be held to determine the cause.
Engineers at the site estimate that they have about two weeks to release the water and so prevent a full collapse.
