LAGOS, March 24 (Reuters) - A four-storey residential building collapsed in Nigeria's biggest city Lagos on Tuesday, killing at least two people, a Reuters witness said.
A Reuters reporter saw rescuers pull two bodies, one male and one female, from the rubble of the building, located in the densely populated Idi-Araba neighbourhood close to the Lagos University Teaching Hospital.
"There are about 14 people so far rescued alive. It was a four-storey building, fully residential. There are still some people trapped inside," Red Cross spokeswoman Umo Okon said.
Construction workers from a nearby site brought excavators to try to lift the roof off the collapsed building and allow rescue workers to get inside.
Substandard materials and disregard for building regulations mean such collapses are not uncommon in Africa's most populous nation, where infrastructure is old and poorly maintained.
Twenty-eight people were killed in 2006 when another four-storey building collapsed in Lagos. The death toll then was high because people were using a restaurant, bar and shops on the ground floor at the time.
At least three people were killed last July when a four-storey shopping centre being built in the capital Abuja collapsed. (For full Reuters Africa coverage and to have your say on the top issues, visit: af.reuters.com/ ) (Reporting by Seun David; writing by Nick Tattersall; editing by Tim Pearce)
A residential four-storey building collapsed in , Nigeria on Tuesday. At least two people have died, and another fourteen people have been rescued from the debris.

The building was located in the Idi-Araba neighbourhood, a densely populated area of the city.

A spokeswoman for the Red Cross, Umo Okon, stated that "there are about 14 people so far rescued alive. It was a four-storey building, fully residential. There are still some people trapped inside."

Construction workers working at another site nearby helped remove the building's roof to help the rescue effort.

Building collapses are not unheard of in Nigeria: In 2006, 28 died after a building, with a restaurant and shops, collapsed in Lagos. In July of last year, three people were killed when another four-storey building came down in , the capital of the country.

It is still uncertain what caused the incident, although collapses such as these have in the past been blamed on poor building standards and low construction material quality.
