Suspected Boko Haram suicide bombers have killed 12 people and injured 48 others in an attack on the north-eastern Nigerian city of Maiduguri, officials from the State Emergency Management Agency (SEMA) for Borno said.

The attack which took place late Wednesday comes in the wake of an extensive military offensive by Nigeria’s military against the Islamist insurgency that has wreaked havoc in the north-eastern state of Borno, the epicentre of militant violence since 2009.

While Abuja has claimed to be winning the war, attacks by Boko Haram have continued to target both the military and civilians.

Two bombers attacked a market in the Muna Garage area, a frequent target of attacks and where a displacement camp is situated, on the outskirts of Maiduguri.

Witnesses said the smell of charred bodies and stale blood was still evident hours following the attack as parts of the market continued to burn after catching fire.

A Boko Haram faction released a video on Monday showing some of the school girls kidnapped from the town of Chibok almost four years ago, as well as a downed Nigerian military aircraft and a group of policewomen abducted last year.
