It is estimated that there are tens of thousands of children in armed groups around the world.
Not all children in armed groups are soldiers. Boys and girls as young as eight may be recruited to fight on the front line, participate in suicide missions and act as spies, messengers and lookouts. Many are lured in my promises of education, security and money, and others are indoctrinated or forced.
The recruitment and use of boys and girls in armed conflict is one of the most horrific violations of children's rights.
At War Child we hold children's rights at the centre of everything we do. We won't stop until every child is safe.
