Expressing "distress" over the "cancer in our system" in the wake of cases in the Central African Republic, Ban said, "Too many incidents go unreported. Too few cases are prosecuted. Too often justice is denied."
The Secretary General said it is critical that troop contributing countries take swift action to appoint national investigation officers, conclude investigations and hold perpetrators accountable.
Ban told the powerful 15-nation Council that he has proposed that his report next year to the General Assembly "include country-specific information on credible allegations that are bing investigated."
He said that he also proposes sexual exploitation and abuse cases be placed on the agenda of the meetings of the Security Council with the troop-contributing countries and called on the Council to review follow-on action on all reported cases.
