FIFTEEN people were killed when a five-storey building collapsed overnight in Fez in central Morocco, local authorities said in issuing a new provisional death toll on Wednesday. Another 37 were injured, including three seriously. Workers are still searching for further victims as well as for survivors. Cracks had recently appeared in the facade of the building, and its 86 occupants had been served with an evacuation order, which they had ignored. In January 1998, a block of flats collapsed in the same district, killing 17 people.
