Bomb at UN building in Nigerian capital Abuja

There has been a bomb attack at the UN building in the Nigerian capital Abuja, the United Nations says.

The ground floor of the building has been badly damaged.
The emergency services are removing bodies from the building while a number of wounded are being rushed to hospital, our correspondent says.
Islamist militants have carried out recent attacks on the city.
A car bombing at police headquarters in June was blamed on Islamist sect Boko Haram, a group which wants the establishment of sharia law in Nigeria.
There has been no claim of responsibility for Friday's attack, but government officials have blamed "terrorists" for the bombing, our correspondent says.
Friday's attack took place at about 1100 local time (1000 GMT) in the diplomatic zone in the centre of the city, close to the US embassy.
There was a loud explosion and smoke billowed from the building. Eyewitnesses told our correspondent that a car bomb had exploded, but that detail is unconfirmed.
"We have deployed our policemen and anti-bomb squad. We can't establish how many casualties [there are]," an Abuja police spokesman said according to Associated Press news agency.
