The trial of the two South Sudanese pastors who were arrested in Sudan will continue in two weeks following witness testimony by the National Intelligence and Security Services (NISS).

A NISS representative testified Sunday at a hearing in Khartoum before the trial was adjourned until 15 June for lack of evidence, according to a source close to the proceedings. The pastors were returned to Omdurman prison after the court hearing.

The source said that family members expressed they want to see their relative freed.

Yat Michael and Peter Yein, both pastors of South Sudan Presbyterian Evangelical Church, have remained in jail for about five months. They were arrested on charges of 'waging war against the state,' under Article 51 of Sudan's Penal Code, and 'spying' under article 53, which are punishable by death and death or life imprisonment, respectively.
