A mosque under construction collapsed on Saturday, trapping an estimated 10 workers in the rubble, an official said. Mayor Hasan Unver told NTV television four other workers were injured in the accident at the building site in town of Acigol, in the central Turkish province of Nevsehir. Their condition was not serious, he said. Unver said the workers were trapped beneath the collapsed dome of a mosque that was being built at an industrial area of Acigol. State-run TRT television showed images of rescuers, some holding a bright orange stretcher, scrambling to rescue one trapped worker amid a pile of rubble and iron rods.
