The 38-year-old Dundalk mother-of-one, who is seeking to return to Ireland after the death of her jihadist husband, has always maintained that she played no part in any acts of terror carried out by the Islamic State.

“Even if I wanted to fight, tried to fight, they would not let me,” she has said previously.

She and her two-year-old daughter are currently being held at the Al Hawl detention camp on the Syrian border with Iraq.

Assistant Commissioner Michael O’Sullivan told RTÉ News that Smith can be prosecuted under the Criminal Justice Act of 2005, which states it is a criminal offense to engage in terror activity inside or outside the state.

O’Sullivan said the Director of Public Prosecutions will determine whether she faces criminal charges.

According to O'Sullivan, Smith is one of two Irish citizens under criminal investigation on suspicion of committing terrorist acts with ISIS. The other is Alexandr Bekmirzaev, who is also being detained in Syria.
