Dominican Republic rescue workers on Wednesday ended the search for survivors of a nightclub roof collapse as the death toll surpassed 180 in the Caribbean nation's worst disaster in decades.

Emergency personnel late Wednesday reported 60 more deaths compared to the morning's count, with the total confirmed tally reaching 184.

An official statement had earlier said that "all reasonable possibilities of finding more survivors" had been exhausted, and the focus of the operation will turn to recovering bodies.
