Two dissident republicans were arrested after heckling a remembrance service in Dublin yesterday morning.
The Duke of Kent, Irish President Michael D Higgins, Northern Ireland Secretary of State Theresa Villiers and Belfast Lord Mayor Nichola Mallon were among the dignitaries at the service at Glasnevin Cemetery.
One eyewitness said there were about 20 protesters in total.
"They were shouting 'shame, shame, shame on you' intermittently throughout the event," he told the Belfast Telegraph.
"But they were kept outside the main cemetery."
The protesters are believed to have been from the 32 County Sovereignty Movement, which is connected with the Real IRA.
There was a report that at one stage the protesters were pepper-sprayed by the Garda after they started screaming obscenities and refused to leave after being asked to do so.
The Garda Press office confirmed that two men in their thirties had been arrested by officers at the scene.
One was arrested at 11.30am and later charged with public order offences.
He appeared in court yesterday afternoon for an initial hearing.
The second man was arrested at around 2pm.
He was charged with public order offences at Mountjoy Garda station.
The man was released on bail but ordered to attend court on August 15.
