In Nigeria, emergency workers have halted their efforts to rescue people in Lagos after at least 10 people were killed when a building collapsed. The top floor of the multi-storey building held a private elementary school. More than 30 people, many of them children, have been rescued from the rubble, but it's unclear how many of the rescued will survive. Now, after one day and night of searching, emergency workers say they are no longer looking for bodies.
