Interior Minister Prince Naif said yesterday that the trial of 13 suspects accused of trying to assassinate Crown Prince Abdullah will start soon after the completion of investigations. "Investigations in such cases will take their course before being referred to courts," Prince Naif told reporters in Riyadh when asked about reports on the imminent trial. Asharq Al-Awsat, a sister publication of Arab News, reported yesterday, quoting Saudi officials that the trial of eight Saudis and five Libyans was likely to start in Riyadh this month. Prince Naif, who arrived from Sanaa after chairing a meeting of the Saudi-Yemeni Border Committee, also said the probe on the assassination attempt was on the verge of completion. "We'll then know all the facts," he added.
