The Tanta Criminal Court on Monday postponed court proceedings in an ongoing case against several Egyptian police officers accused of killing unarmed anti-regime protesters during last year's 18-day Tahrir Square uprising to 28 January.
Four security officials and three officers from the Gharbiya Security Directorate face charges of killing 15 protesters and injuring another 60.
Court proceedings have so far been conducted under heavy security, with military and police forces surrounding the court complex in Tanta, capital of Egypt's western Nile Delta Gharbiya governorate.
Most police officers charged with killing political demonstrators during last year's popular uprising have so far been acquitted, while the rest continue to face trial. None have yet been convicted.
More than 1000 Egyptians have been killed by security forces since the outset of last year's revolution, while at least 1000 remain missing.
