U.N. Secretary-General Antonio Guterres warned Tuesday that “a wind of madness is sweeping the globe,” pointing to escalating conflicts from Libya and Yemen to Syria and beyond. Guterres singled out Libya where he called the current offensives by the warring parties “a scandal” — coming soon after world powers and other key countries adopted a road map to peace in Berlin on Jan. 19 that called for respect for a U.N. arms embargo, an end to foreign interference in the fighting by rival governments and steps toward a cease-fire.
