A car bomb in Nigeria has killed at least 18 people at a bus terminal on the outskirts of the capital, Abuja.
Police say dozens of people were wounded late Thursday in the blast that occurred near the site of an April 14 bombing at a bus station that killed at least 75 people.
The Islamic extremist group Boko Haram claimed responsibility for the April blast. No one has claimed the latest attack.
Nigeria is planning to host the World Economic Forum on Africa next week. President Goodluck Jonathan has promised extraordinary security measures for the meeting.
Jonathan said Thursday that Nigeria will triumph over what he calls the evil that wants to debase humanity.
Boko Haram has killed thousands in a five-year insurgency to set up a hardline Muslim state in northern Nigeria.
Militants from the group are suspected in the kidnapping of more 250 schoolgirls in northern Nigeria more than two weeks ago. Some reports say the militants are forcing the girls into marriage.
