An explosion has hit a bus station in Nigeria's capital and many people are feared dead.
The blast Monday in Abuja happened as people were traveling to work.
There was no immediate claim of responsibility for the attack.
The Islamist militant group Boko Haram often carries out attacks in its attempt to create a strict Islamic state in the northern part of Nigeria.
Last week, suspected Islamists killed at least 60 people on an attack in Borno State.
Boko Haram has been blamed for thousands of deaths since launching an insurgency against the government in 2009.
Amnesty International said two weeks ago that 1,500 people have died in Boko Haram-related violence this year alone.
