A County Down court has heard that an extreme right wing group had a 15-point plan to attack a Galway city Mosque.
Details of the alleged plan, which would have involved five people, were revealed at Downpatrick Magistrates' Court during a bail application by a 38-year-old man facing terror charges.
Connor Pollock, of Croob Park in Ballynahinch, Co Down, appeared by video link.
He's accused of withholding information about the preparation of a terrorist act.
The charge relates to a planned attack on the mosque in Ballybrit by a group calling itself the Irish Defence Army.
He is also charged with possession of documents or records useful to terrorists.
That relates to his alleged possession of a claim of responsibility by the same organisation for the burning of a mosque.
The same document included threats of violence against facilities for migrants and those providing them, warning that they would be regarded as "legitimate targets".
Refusing the application for bail, Deputy District Judge Liam McStay said messages on Mr Pollock’s phone "seem to indicate he is more than a bystander".
Connor Pollock was remanded in custody to appear in court again next month.
