Two people have died after a helicopter crashed into a residential building in Nigeria’s commercial capital, Lagos, the authorities say.

Friday’s accident happened in the Ikeja district, a congested part of the state popular for its businesses and residential apartments.

Head of the state emergency agency, Olufemi Oke-Osanyintolu, told local media that there were three people in the helicopter when it crashed and the third person was severely injured and has been taken to hospital.

A video posted on social media shows onlookers gathering around and what appears to be part of the wreckage.

It is not clear who owns the helicopter and what led to the accident, but Nigeria’s busiest airport, the Murtala Muhammed International Airport is situated in the area and is used by small aircraft and private jets.
