A bomb blast at the United Nations building in Nigeria’s capital, Abuja, has killed at least 16 people.
Witnesses report seeing a vehicle force its way past security and explode once it reached the four-story building on Friday morning.
Rescuers raced to pull bodies and survivors from the rubble at the compound.
Speaking from New York, U.N. Secretary-General Ban Ki-moon predicted the casualty toll will be “considerable,” but added he did not yet have an exact number.
