Is Boko Haram repositioning itself? By Tomi Oladipo, BBC Monitoring's Africa security correspondent
Boko Haram appeared to be on the back foot following a military campaign by the Nigerian army and its allies from neighbouring countries. This raised questions over whether the IS link had been of any benefit.
But recently the group has stepped up its attacks against regional security forces. A UN convoy was also ambushed last week in north-eastern Nigeria. Even on social media, the jihadist group has resumed its propaganda campaign.
The increase in attacks could worsen the humanitarian situation around the Lake Chad region, where tens of thousands of people remain in miserable conditions in overcrowded camps.
Aid agencies also warn that children are dying there in large numbers from malnutrition.
