Boko Haram has claimed responsibility for the bomb blast at the police headquarters in Abuja on Thursday which claimed about 2 people and injured several others.

A man claiming to be the spokesman for Boko Haram told international news agency Voice of America [VOA] in an interview that Boko Haram is responsible for the attack and intends to do even more.

The acclaimed Spokesman, Usman Alzawahiri said " yes, the blast is their handiwork. We are behind it,and we are going to attack the entire north and other parts of the country, including the capital, Abuja".

Alwaziri revealed that Boko Haram personnel just returned from Somalia five days ago and have been scattered around northern parts of the country, he said they are advising everyone to be wary.

Earlier this week, the group had laid out its conditions for a ceasefire and government-proposed peace talks.

However, Alzawahiri told VOA that for the moment, those efforts at reconciliation had collapsed and security agencies should prepare for intensified attacks.

Boko Haram claimed responsibility earlier this month for a series of bombings that killed 16 people after President Goodluck Jonathan's inauguration.

The group is also blamed for the killings of Muslim and Christian religious leaders and at least three bomb attacks this month in Borno State.
