A decision has to be made before 10.30 this morning on whether to charge Lisa Smith or release her from Garda custody.
The 38-year-old has spent a third night in custody while she is being questioned over alleged terrorist offenses.
The Dundalk woman was arrested on Sunday morning after she returned to Ireland on board a Turkish Airlines flight from Istanbul with her 2-year-old daughter.
She travelled to Syria three years ago to join the so-called Islamic State group but maintains she wasn’t involved in fighting.
She had her period of detention extended to a third day and was still being questioned by members of the Garda Special Detective Unit overnight.
The Dundalk woman is in custody as part of a criminal investigation into alleged terrorist offences.
She's still being held in Kevin Street garda station in Dublin, but her period of detention can't be extended again and we should know this morning whether she is to be released or charged.
