Two years after Omar al-Bashir's whirlwind visit to South Africa, judges at the International Criminal Court unanimously ruled the nation's officials erred by failing to arrest Sudan's president on an international war crimes warrant.

The court issued a warrant in 2009 for the Sudanese leader on charges of genocide, war crimes and crimes against humanity for his involvement the long-running conflict in Darfur, where the United Nations estimates 300,000 people have been killed and more than two million have been displaced.

Other African nations and the African Union have frequently accused the court of targeting Africans. The court disputes this charge and notes it is investigating situations in a number of countries, but has yet to try a case from a non-African nation.
