Rescuers were using cranes, drills and their bare hands to try to reach dozens of people trapped when a multi-storey building being built in the South African city of George collapsed, killing at least seven people. Of the 75 workers who had been on the construction site, about 48 remained unaccounted for on Tuesday. Authorities have made no comment about what caused it to collapse on Monday.
