Irish teenager Ibrahim Halawa's trial in Egypt has been postponed until 2nd August, according to his family.

The 19-year-old from Dublin is due to face trial this morning - almost two years after being detained in Cairo.

Ibrahim had been due to begin his studies at Trinity when he was arrested in August of 2013 as he was attending a protest in the Egyptian capital.

His trial, and that of almost 500 others, has been adjourned a number of times. It was last postponed in April.

Ibrahim's sister Nusayba spoke to Jonathan Healy on Newstalk Lunchtime after today's news. She explained what happened, and says she fears for her brother's life:

Amnesty International has raised serious concerns about Ibrahim's health and well-being. Amnesty International Ireland's Colm O'Gorman, speaking before the latest postponement, says there is no end in sight for the teenager:

Last month it emerged that Ibrahim Halawa is not facing the same charges as some of the others within his group trial.

The Taoiseach told the Dáil that Mr Halawa has been accused of lesser crimes than was originally thought, and “more preliminary charges” than some of those he has been grouped with.

There are four charges against Mr Halawa, Enda Kenny said, which are:

“Presence inside the mosque at the time of arrest; refusal to leave the mosque when requested to do so and when offered safe passage by military police; travelling from a different part of the city with the intention of getting involved in a protest; and assisting in locking and barricading the mosque from the inside, according to photo and video evidence.”
