An Irish citizen who became an Islamic State bride has been arrested after arriving back in Dublin.
Lisa Smith and her daughter travelled from Turkey after being deported, arriving in Ireland on Sunday.
She was arrested on arrival and it is expected she will now be interviewed by police about suspected terrorist offences.
Plans have also been made for the care of her two-year-old daughter, who was born in Syria, but is an Irish citizen.
Miss Smith is a former member of the Irish Defence Forces.
In a statement, Irish Minister for Justice Charlie Flanagan said: “This is a sensitive case and I want to reassure people that all relevant state agencies are closely involved.”
Irish state broadcaster RTÉ has posted footage on social media of her being escorted by gardaí (Irish police) on the runway in Dublin.
The BBC interviewed her in Syria earlier this year.
She said was not involved in fighting and did not train girls to become fighters.
She also claimed she had been visited more than once by the FBI for questioning, and agents had taken her fingerprints and DNA.
Ms Smith had been living with her daughter in a Syrian refugee camp.
The taoiseach (Irish prime minister) Leo Varadkar had previously said she would “certainly” be investigated if she returned to Ireland.
