The UN’s top humanitarian official Jan Egeland is in war-torn Cote d’Ivoire seeking assurances from authorities that January’s anti-UN violence will not be repeated and that ringleaders of the attacks will be punished. “To those who have carried out criminal behaviour - attacking humanitarians or civilians - we are coming with a message that stimulating violence or attacking has to be punished,” the UN Under-Secretary-General for Humanitarian Affairs said in the main city Abidjan on Wednesday.
