A TWO-DAY summit called by the Organisation of African Unity and slated for March 30-31 has been cancelled, Burkina Faso’s presidential office said on Wednesday. Burkina Faso, current holder of the OAU’s rotating presidency, called the summit, which was to have been held in its capital Ougadougou, to “examine initiatives and mediation efforts under way to seek root causes of conflicts in Africa”. The conflicts in Angola and the Democratic Republic of Congo were of particular concern.
