Explanation:

Child Soldier refers to any person below 18 years of age who has been, recruited or used by an armed force or armed group in any capacity.

• It includes but is not limited to children, boys and girls who are used as fighters, cooks, porters, spies or for sexual purposes (Paris Principles on the Involvement of Children in Armed Conflict 2007).
• The recruitment or use of children below the age of 15 as soldiers is prohibited by both the UN Convention on the Rights of the Child (CRC) and the additional protocols to the Geneva Conventions.
• The Geneva Conventions and their Additional Protocols form the core of international humanitarian law, which regulates the conduct of armed conflict and seeks to limit its effects.
• They protect people not taking part in hostilities and those who are no longer doing so.
• Recruiting Child Soldiers is also considered a war crime under the Rome Statute of the International Criminal Court (ICC).

Hence all statements are correct.
