Six people have been killed in three bomb attacks in the northeastern Nigerian state of Borno.
The bombings were carried out in Maiduguri, Borno's capital, on Friday.
One of the explosions rocked Jiddari area near a mobile police post, Borno state police commissioner Damian Chukwu told reporters in Maiduguri.
The official added that two other bombings were carried out "along Maiduguri-Gamboru road."
The Boko Haram Takfiri terrorists have claimed responsibility for the bombings.
Police said four assailants and two civilian defense fighters were killed in the bombings. One of the attackers was arrested.
Maiduguri has been the epicenter of Boko Haram's seven-year insurgency.
Borno has taken the brunt of Boko Haram's acts of terror, which started in 2009.
The group has recently regained momentum after it was nearly obliterated months ago by a joint military force made up of Nigerian government forces and troops from neighboring countries.
Boko Haram has pledged allegiance to the Daesh Takfiri terrorist group, which is mainly active in Syria and Iraq.
The United Nations has warned that areas affected by Boko Haram face a humanitarian crisis.
Boko Haram terrorists have so far killed more than 20,000 people and forced over 2.7 million others from their homes.
The group started its campaign with the aim of toppling the central government in Nigeria.
