KARACHI: The death toll from a collapsed multi-story residential building in southern Pakistan rose to 16 as search operations to find survivors continued for the second day.Rescuers pulled 10 more bodies from the rubble during an overnight operation, officials said Saturday.The govt-run Civil Hospital said in a statement it had received the 16 bodies, adding several of the injured had been hospitalised. Rescue workers are using heavy machinery to search for at least eight more survivors believed to be trapped under the debris, said emergency officials.Residents said the building was located on a narrow street, hampering efforts to bring in additional heavy equipment. Television footage showed rescuers removing debris as relatives of those still trapped cried and prayed for the safety of their loved ones.Building collapses are common in Pakistan, where construction standards are often poorly enforced. Many structures are built with substandard materials, and safety regulations are frequently ignored to cut costs. In June 2020, an apartment building collapsed in Karachi, killing 22.
