Eleven people were killed when Boko Haram gunmen and suicide bombers launched a rare combined attack inside the strategic northeast Nigerian city of Maiduguri, police said on Thursday.

Borno state police commissioner Damian Chukwu said one civilian was killed as locals in the Jiddari Polo area of the city fled, while 10 were killed nearby in three separate suicide blasts.

Wednesday night's attacks took place on the eve of a visit by Vice President Yemi Osinbajo, deputising for unwell President Muhammadu Buhari, to launch a major humanitarian aid programme.

The raid came barely a month after a senior Boko Haram commander threatened to attack the city after he was released from government custody in exchange for 82 kidnapped schoolgirls.

The raid will likely raise fresh fears about the extent of government and military claims that the Daesh group affiliate is all but defeated.

Fighters thought to be loyal to the group's embattled factional leader Abubakar Shekau stormed the Aridawari settlement, firing heavy weapons, including anti-aircraft guns, and burning down homes.

Residents said they then drove towards a military base through the Jiddari Polo area, firing guns and forcing locals to flee, before they headed towards the Giwa military barracks.

Chukwu said police and troops from the Nigerian Army 7th Division stationed in Maiduguri were deployed and "repelled the attack in a gun battle that lasted about an hour."

"A civilian whose identity is yet to be ascertained was killed in a stampede while a soldier was reported wounded. Normalcy has been restored," he said in a statement.

The police commissioner said the first of the three suicide bomb attacks happened in the Goni-Kachallari area of Maiduguri and targeted worshippers leaving a mosque.

"The suicide bomber and six others died, while 18 others were injured," he said.

"The second suicide bomber detonated within the premises of the Chad Basin Development Authority in Maiduguri at about 2120 hours (2020 GMT)," he added.

"The suicide bomber and three others died. The third suicide bomber detonated across the road outside the CBDA premises, killing himself and one other person."

Twenty-four people were injured in all three bombings, he said.

Hit-and-run raids were once a regular feature of Boko Haram's insurgency, which since 2009 has left at least 20,000 people dead and displaced more than 2.6 million others.

On December 27, 2015, just days after Buhari said the group was "technically defeated," a raid and suicide bomb attack killed 22 in Jiddari Polo.
