A man has been remanded in custody after appearing in Dungannon Magistrates' Court charged with the murder of 29 people in the Omagh bombing in 1998.
Séamus Daly, 43, from Culloville in Co Monaghan, did not speak during the hearing.
A PSNI detective inspector said he could connect Mr Daly with the charges on the basis of witness and forensic evidence.
Mr Daly has been charged with 29 counts of murder, two charges linked to the explosion in Omagh and two other counts linked to an attempted explosion in Lisburn in April 1998.
A small number of relatives of the Omagh bombing victims sat in the public gallery for the short hearing.
The bombing by the Real IRA was the single biggest atrocity of the Troubles.
Mr Daly was one of four men found liable of the atrocity in a civil case in 2009 brought by the victims' families.
Bail was refused for Mr Daly and he will appear in court again next month.
