(Child Soldiers International) – Children were used to fight in at least 18 conflicts since 2016 – including as ‘human bombs’ – despite a global ban on the use of children in war, a database showed on Wednesday. Child soldiers were used in Syria, Libya, Nigeria and Colombia – all of which have ratified a United Nations treaty outlawing the conscription of under 18s and their participation in hostilities, the campaign group behind the index said.
