At least 18 people have been killed in Nigeria following an attack on the United Nation’s headquarters in the capital, Abuja.
The Red Cross says another 11 people were injured after a bomb exploded outside the UN building, and that the death toll is likely to rise.
The police say a lone bomber arrived outside in a car before ramming the entrance and detonating his device.
“These buildings house 26 humanitarian and development agencies of the United Nations family. This was an assault on those who devote their lives to helping others. We condemn this terrible act utterly,” said UN Secretary General Ban Ki-Moon.
Police say the attack could be the work of Islamic militants Boko Haram, who have been active since last year’s presidential elections split northern mostly Muslim Nigeria and the animist and Christian south , or al-Qaeda in the Islamic Maghreb, which has recently become more active in the country.
