At least three people have died after a building collapsed in Kenya's capital, Nairobi.

As we reported earlier, a search operation was underway to rescue at least 10 people, most of whom were thought to be construction workers.

Reports now say that six people have been rescued from the seven-storey building which was still under construction.

A supervisor in charge of the site twice ignored warnings from authorities to stop construction work following concerns over its stability, the Nation news site reports.

The collapse of buildings under construction is not uncommon in the city.
