On Friday, the Nigerian government repatriated 22 family members of suspected former members of the Islamic State (ISIS) killed in Libya.
The 22 people, including children, are said to be part of 101 stranded Nigerians repatriated to the country and were received by officials of the Ministry of Foreign Affairs.
In 2015, Boko Haram pledged allegiance to ISIS.
The Institute for African Security Studies (ISS) warned that ISIS adopts a complex network of communications and roads across West and North Africa to facilitate the movements of its affiliated militants.
Earlier, the Nigerian authorities admitted, for the first time, that militants had shot down a military plane, but the concern is that the attack was carried out using high-grade Libyan weapons.
This incident comes days after a security report revealed that ISIS is currently re-deploying its forces in the Lake Chad basin and the African Sahel region.
