The plan by four suicide bombers to hit a target in Maiduguri on Sunday failed, as the bomb went off, killing all four of them.
The target, according to the National Emergency Management Agency, is a military checkpoint at the city centre in Maiduguri. But the terrorists barely reached the point before they ended their lives.
Their remains have been deposited in a mortuary at the specialist Hospital in Maiduguri.
After news of the botched attack filtered into town, the Borno State governor, Kashim Shettima, summoned a meeting of some prominent community leaders and Emirs, on how to end insurgency in the state.
Maiduguri has been under serious attacks from the terrorists in the last two weeks. On Friday, two female suicide bombers attacked a mosque, killing six people.
Also on Friday, a suicide bomber, ran into a mosque in Yola, Adamawa state, killing 16 people.
In all, 22 people were killed in one day, in the north east.
No group has claimed responsibility for the attack.
But a terrorist group, the Boko Haram, has carried out similar attacks in the past.
