Deadly building collapse in Nigeria

Two people have died after a four-storey building collapsed in Lagos in southern Nigeria.Another 14 people were pulled from under the rubble of the residential block in the city's densely populated Idi-Araba neighbourhood on Tuesday, with others feared trapped, rescue workers said.One male and one female were killed during the incident near to Lagos University Teaching Hospital in the country's largest city."There are about 14 people so far rescued alive. It was a four-storey building, fully residential. There are still some people trapped inside," Umo Okon, a Red Cross spokeswoman, said.What caused the building to collapse was not immediately apparent, and the police are yet to comment.Construction workers close by helped to remove the roof of the building to aid rescue attempts.Poor quality materials used in construction and negligible building standards in Nigeria are often blamed for such collapses.
