In northern Borno state, the epicentre of a conflict that has spread to three neighbouring countries – Chad, Cameroon and Niger – Nigeria’s army has unleashed a barrage of air and land assaults.
The counterinsurgency has clawed back some territory, but Boko Haram has responded by stepping up guerrilla tactics, ambushing troops and attacking civilians.
In late November, Major General Leo Irbor hailed his men’s success in freeing “more than 5,200 people” in a month.
But the high number of people freed highlighted Boko Haram’s capacity to capture and hold vast, heavily populated areas.
Villagers under siege are typically forced to abandon their crops, devastating local food supplies. Those who escape Boko Haram are generally transported by the army to camps where basic supplies are also desperately scarce.
‘Scorched-earth’
The scale of humanitarian suffering has become more apparent as troops recapture and discover the “scorched-earth” conditions of villages that have fallen to the hands of Boko Haram.
But some local people complain that there are not enough security forces deployed to battle the group.

The same day as Irbor made his comments, five people were killed in raids on villages near Chibok, the district that gained notoriety for the Boko Haram kidnapping of more than 200 schoolgirls in 2014.
The Boko Haram raiders looted and burned houses, set fire to crops that were ready for harvesting, and killed the locals – even though the army had been alerted to the assault.
“We’ve heard there are 700 soldiers to secure the zone bordering the Sambisa forest that is the Boko Haram stronghold,” said Ayuba Alamson, a resident of Chibok.
“We need another battalion,” said Alamson.
Though Boko Haram has been weakened and casualty numbers followings its attacks are often low, the frequency of their strikes “enable it to keep up the pressure on security forces and force them to deploy”, said Omar Mahmood, a researcher at the Institute for Security Studies, stretching them further.
‘Famine-like’
Troop numbers are also being pulled away to fight on another front in the south where fighters have been sabotaging oil pipelines and other installations vital to the country’s export earnings in a fierce dispute over local autonomy and the distribution of petrodollars.
The number of killings in the northeast, which increases after the end of the rainy season each year, is a particular cause for concern – especially on the border with Niger.
Territory in Niger has become the stronghold of Abu Musab al-Barnawi, who was declared a local leader by the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) armed group after Boko Haram declared allegiance to them.
Yan St-Pierre, director of the Modern Security Consulting Group, said that pressure on ISIL fighters in northern Libya has pushed its activities further south, to countries bordering Nigeria.
As a result, their “effectiveness for supplying [fighters] with weapons and logistic material has greatly improved over several weeks,” he told the AFP news agency.
