ONE Nigerian worker was killed and 14 were missing after a half-built office block collapsed in the capital Abuja on Wednesday, state-run television said. The body of the dead man was pulled from the building while work continued to rescue the others still under the rubble, the NTA television station said. The cause of the collapse and the exact location of the building were not given. Building standards in Nigeria are often poor and building collapses occur frequently. – Sapa
