Army blames spate of attacks including live fire, explosives and burning of buildings on Boko Haram.

Gunmen suspected of belonging to the Boko Haram group have killed at least seven people in separate attacks in Nigeria’s volatile north, the police and army said.

In the first attack on Friday, gunmen opened fire and threw explosives at several targets including a police station, a prison and government offices in Maiha, a northeastern town along the border with Cameroon, leaving two dead, police said.

“Two people were killed in the attack. We lost a policeman in the attack on the police station and a civilian was also killed at the government lodge,” Adamawa state police spokesman Mohammed Ibrahim said.

“The attackers burnt down the police divisional headquarters, a court, a satellite prison, a local education authority building and the government lodge,” he said, adding that the palace of the town’s traditional chief was also partially torched.

No arrests have been made, he said.

Andrew Barka, head of prisons in the state, said inmates had been released during the prison attack.

“The satellite prison in Maiha was broken into and burnt by the attackers. They freed inmates before setting the prison on fire,” he said.

Ibrahim, the police spokesman, said that 35 inmates had escaped. Eleven of them were recaptured.

Boko Haram

In a related development also on Friday, Lieutenant Colonel Sagir Musa, the military spokesman in Maiduguri, the epicentre of previous deadly attacks blamed on Boko Haram, said some gunmen killed five people in their homes outside the city.

“Information revealed that some terrorists sneaked into Musari, a village located on the outskirts of Maiduguri and secretly carried out selective killings of five people, including a serving Nigerian police traffic warden,” he said.

He said troops responded to the attack, arresting three suspects and recovering one AK-47 rifle with 10 rounds of ammunition.

No group so far has claimed responsibility for the deadly attacks.

Violence linked to the Boko Haram is believed to have left some 3,000 people dead in Nigeria since 2009, including killings by the security forces.

Boko Haram is thought to include various factions with differing aims, in addition to imitators and criminal gangs that carry out violence under the guise of the group.

Its targets have included Christian churches as well as symbols of the establishment, including police and other security agents.
