Judges at the International Criminal Court today ordered an alleged Congolese warlord to be tried on charges he recruited child soldiers and sent them into battle, making him the first suspect to stand trial at the permanent war crimes court.

Slobodan Milosevic, architect of the Balkan conflicts that produced Europe’s worst atrocities since World War Two, is to appear before a United Nations judge on Tuesday to enter a plea on war crimes charges.

Slobodan Milosevic arrived in The Hague early today, hours after Serb authorities handed the former Yugoslav president over to the UN war crimes tribunal to face charges of ‘‘crimes against humanity.’’
