The militants invaded a base holding hundreds of soldiers in Yobe state, where they abducted over 100 girls from a school earlier this year, in an hours-long onslaught Saturday night, a military source told AFP on condition of anonymity.
The attack took place after Boko Haram fighters ambushed a military convoy in neighbouring Borno state on Friday, highlighting the tenuous hold Nigerian forces have on the remote region despite claims from Muhammadu Buhari’s government the country is in a “post-conflict stabilisation phase.”
“Boko Haram terrorists attacked troops of the 81st Division Forward Brigade at Jilli village in Geidam district. The terrorists came in huge numbers around 7:30 pm (18:30 GMT) and overran the base after a fierce battle that lasted till 9:10 pm,” said the military source.
“The base had 734 troops. Currently the commander of the base and 63 soldiers have made it to Geidam (60 kilometres away) while the remaining 670 are being expected,” he said.
“We don’t know if there were any casualties among the troops. That will be known later,” he said, adding that the base was new and the troops had recently arrived from Lagos, the commercial capital.
A leader of a local anti-jihadist militia said that the soldiers sustained casualties, but was unable to give a toll, attributing the attack to the Abu-Mus’ab Al-Barnawi faction of Boko Haram, which is known for targeting Nigerian forces.
“We learned that they drove from Lake Chad through Gubio (in nearby Borno state) and attacked the base,” he said.
Geidam resident Fannami Gana said that Boko Haram jihadists “overwhelmed” the troops.
“We don’t know the details of what happened but we learnt they were overwhelmed by hundreds of Boko Haram gunmen,” said Gana.
On Friday, 23 Nigerian soldiers went missing after Boko Haram ambushed a convoy outside Bama, leading to the loss of several military vehicles.
According to a military officer, “around 100 terrorists” attacked the convoy.
The sophisticated attacks highlight the continued threat, and evolution, of Boko Haram, an Islamic State group ally, said Yan St-Pierre, counter-terrorism advisor and head of the Berlin-based Modern Security Consulting Group.
St-Pierre suggested that the attacks could be because Boko Haram fighters are vying for control of the faction led by Abubakar Shekau, the long-time jihadist leader who is reportedly ill.
“When a near-mythical leader is on his way out there’s always a battle to establish who could be next,” said St-Pierre.
The attacks show the persistent threat of Boko Haram in the Lake Chad region, said the security expert.
As the jihadists exploit rampant poverty in the region, the Nigerian army, which is overstretched and under-resourced, struggles to keep the insurgency in check.
“The supply of Boko Haram fighters is always there, either through kidnapping or economic reasons, they tap into a wide pool of personnel, they find a way to replenish their strength,” St-Pierre said.
President Buhari, a 75-year-old former military ruler, came to power three years ago on a promise to defeat Boko Haram.
But while there have been clear military gains since a counter-insurgency was launched in 2015, suicide bombings and raids remain a constant threat, particularly to civilians.
Boko Haram’s Islamist insurgency has devastated the region since 2009, leaving at least 20,000 dead, displacing more than two million others and triggering a humanitarian crisis.
