Nelson Mandela is bringing Burundi’s civil war to the United Nations spotlight as part of a new effort to revive peace talks and end a conflict that has left more than 200,000 people dead and tens of thousands in dire humanitarian straights. Mandela is the featured speaker at an open meeting today of the Security Council, which is expected to adopt a resolution condemning a recent surge of violence in the small central African nation that threatens to explode. Burundi’s civil war has been raging for six years, but it’s not received the international attention of other conflicts, even those in Africa. Donor nations have provided only 17 percent of the more that $83 million requested last year by UN agencies to provide basic humanitarian aid to Burundians.
