(Al Jazeera) – Nine years of war against Boko Haram in northern Nigeria has taken a toll on young people. The Nigerian Army has released a group of children in Borno State after the children were cleared of ties with the group. Experts say more than half a million children require urgent social and psychological support, but facilities available can only look after a few hundred at a time. The fear is some will rejoin Boko Haram.
