(VOA) – A senior U.N. official warns that increasingly children are being killed, maimed, and recruited as soldiers and suicide bombers in armed conflict.  Leila Zerrougui was appointed the U.N. Special Representative of the Secretary-General for Children and Armed Conflict in 2012.  She says the plight of children has worsened every year under her watch. 2015 is shaping up to be the worst year of all.
