Nemtsov murder suspects' arraignment expected, but no official information

A day after Russia announced the detention of two suspects in the killing of prominent opposition figure Boris Nemtsov, there's no official information on their whereabouts.

A crowd of journalists gathered Sunday outside a Moscow courthouse amid expectations that the suspects would be arraigned there. But journalists were not let into the courthouse and telephone calls to the court went unanswered.

A prisoner transport truck pulled into the court's parking area in the morning, but it could not be seen if anyone was discharged from it.

Details remain vague in the case despite President Vladimir Putin's pledge to pursue the killers vigorously. The Federal Security Service said Saturday that two suspects were detained, but did not specify how they were allegedly involved in the shooting of Nemtsov on Feb. 27.
