The U.S. decision to go to war in Iraq without the approval of the U.N. Security Council was "illegal," Secretary-General Kofi Annan told the BBC. "I hope we do not see another Iraq-type operation for a long time _ without U.N. approval and much broader support from the international community," he said in an interview Wednesday with the BBC World Service. Annan said the wave of violence engulfing Iraq puts in doubt the national elections scheduled for January. There could not be "credible elections if the security conditions continue as they are now," he told the BBC.
