On the 10th and 11th April, a spiritual retreat took place at the Casa Santa Marta, (in the Vatican), with the leaders of South Sudan, Salva Kiir and Riek Machar, the most prominent figures in the South Sudanese conflict. The retreat ended with the presence of Pope Francis, who called for peace, but in such a special way that the whole world took notice: he got down on his knees and kissed the feet of the leaders responsible for the conflict, one by one, and without exception.
