Taoiseach Leo Varadkar has said an Irish woman arrested in Syria and her two-year-old son have the right to return to Ireland.
Mr Varadkar said that removing Irish citizenship from them and rendering them stateless would not be the right thing nor the compassionate thing to do.
However, he added it would not be a simple case of coming to Ireland and "proceeding as though nothing has happened".
Mr Varadkar said a security assessment would have to be carried out and Syrian authorities would have to decide if they wanted to prosecute the woman.
If the woman did return to Ireland, he said, a decision would have to be made on whether she poses a security risk.
Gardaí are aware of a female former member of the Defence Forces who became radicalised and travelled to Syria but there has been no contact with her since.
Gardaí have said the woman, who is in her late 30s, converted to Islam eight years ago while she was in the Defence Forces and it is understood she sought to wear a hijab while serving.
The Department of Foreign Affairs has confirmed that an Irish citizen is being detained in northern Syria, but has not confirmed their identity.
Members of the Muslim Community in Ireland have called on the government to consult them about dealing with the return of those who have been radicalized.
Dr. Ali Selim of the Islamic Cultural Centre in Clonskeagh said it was "rational and not emotional" to allow the return of citizens who have been involved with extremist groups.
He said Ireland had a history of neutrality and should use that to help rehabilitate any citizens who have been involved with extremism.
Dr Selim said such an approach would "strengthen our security system".
