The death toll rose to 14 in a building collapse in southern Pakistan's Karachi, as the rescue work is still in progress at the site of the five-storey building collapsed late Friday night, local TV reports said Saturday. The building was located in the Mithadar area and the killed included three members of a family. At least 50 people are feared to be still trapped under the rubble. The adjacent building has also declared dangerous and the residents have been evacuated. The rescue operation was hindered tremendously by the narrow lane in which the fallen building was located. Informed sources said removal of debris could take more than 12 hours. Sindh Provincial Health Minister Sagheer Ahmad has declared emergency in civil hospitals. On July 21, a four-story building under construction collapsed in downtown Karachi, the commercial hub of Pakistan, killing at least 11 persons.
