Defence lawyers in the mass trial are expected to begin challenging video evidence
The defence team will begin challenging video evidence in the Ibrahim Halawa trial in Egypt today.
They will be challenging evidence that has been examined by an expert technical committee appointed by the court.
The committee identified two out of the 494 defendants in the case - and Ibrahim was not one of them.
Mr Halawa, from Firhouse, has been held in an Egyptian jail since his arrest during demonstrations against the ousting of president Mohammed Morsi in August 2013.
The mass trial has already been adjourned 26 times.
Executive Director of Amnesty International Ireland, Colm O'Gorman, explains: "What we're expecting [today] is that a very small, limited number of lawyers for the defence in this trial [...] will challenge evidence that relates to only two out of the many hundreds of defendants in the case.
"We don't expect an awful lot more to happen today, which means the completion of this trial involving Ibrahim is likely to be further delayed."
