Nigerian Authorities say 559 ex-Boko Haram members have graduated from a de-radicalisation programme and are expected to be reintegrated into society soon.
Over the weekend, a deradicalisation centre in the north-eastern state of Gombe hosted a graduation ceremony.
At the event, the graduates pledged their allegiance to the Nigerian authority they had earlier fought against.
The Nigerian government launched the military-led effort in 2015, and it went live in 2016 as part of its counter-terrorism strategy.
Boko Haram members who willingly lay down their arms and surrender to the police receive specialised training, including occupational skills, religious reorientation, and psychological care, before being reintegrated back into society.
The total number of those who have successfully finished the program presently stands at 1,629.
Given the extent of violence perpetrated by Boko Haram, there is still widespread suspicion of former members of the organisation.
The Boko Haram insurgency, which began in 2009, has resulted in the murder of around 350,000 people and the displacement of millions more in Nigeria,Cameroon, Niger Republic and the Lake Chad region.
