The death toll in a building site accident in northeastern Germany rose to five on Saturday when relief workers recovered three more bodies from the rubble of a collapsed wall, local officials said. The initial toll was two when a wall collapsed while workers were carrying out refurbishing work on a school building made of prefabricated concrete slabs. The bodies of three more workers were recovered early Saturday. Five other workers were injured, some of them seriously. The exact cause of the accident was still being investigated. Initial reports said that the scaffolding on which the workers were standing first collapsed, and then took the wall of the building down with it. The school's pupils were not endangered by the accident as that part of the building had been vacated for the refurbishing work. Goldberg, in the midst of the scenic lake district of northeastern Germany, is located about 110 kilometres northwest of the capital Berlin.
