At least 70 people have been killed and over 100 injured in a double bomb attack in the Nigerian capital Abuja. The explosions went off near a crowded bus station on the outskirts of the city.

The explosions ripped through the Nyanya station roughly three miles south of Abuja.

Some 30 vehicles were also destroyed in the blast.

The Nigerian President Goodluck Jonathan has reportedly visited the scene of the attacks, denouncing "the activities of those who are trying to move our country backwards".

Security experts suspect the explosion was inside a vehicle.

Bloody remains could be seen on the ground as security forces struggled to hold back a crowd of onlookers, and fire crews hosed down a bus still holding the charred bodies of commuters.

The city has been hit by a number of similar bomb attacks by Islamic militants in the past.

No group has yet claimed the apparent attack, but suspicion is likely to fall on Islamist militant group Boko Haram, which has waged an increasingly bloody insurgency in the northeast.
