An Irish citizen aligned to Daesh deported from Turkey along with her two-year-old daughter was arrested on her return to Dublin on Sunday on suspicion of terrorist offences, Irish police said.
Ireland agreed to repatriate Lisa Smith, 38, and her two-year-old daughter after Ankara began deporting foreign citizens linked to Daesh earlier this month.
Turkey says it has captured 287 terrorists in northeast Syria, where Turkish troops launched an offensive against the terrorist YPG last month, and has hundreds more terror suspects in detention.
Dublin has said for months that it has a responsibility to bring Smith back to Ireland and that its main concern was for the safe repatriation of her daughter.
The girl was now being cared for by relatives, police said.
