Four people have killed in a bomb blast at the Moru-Moru market in the Gamboru area near Maiduguri the Borno State capital.
Our correspondent in Maiduguri, Blessing Tunoh reports that the explosion is believed to have been caused by a concealed improvised explosive device.
The bomb attack comes barely 24 hours after a suicide bomb attack on a mosque in Maiduguri.
Early on Saturday soldiers had repelled an attack by the Boko Haram sect as they attempted to invade Maiduguri, the Borno State capital.
The insurgents are reported to have approached Maiduguri through Dala, a suburb of the town but could not gain entrance because of the military troops stationed there.
More details soon.
