Two suspected dissident republicans have been arrested by gardaí over the murder of a prison officer in Northern Ireland.
The men, who are aged 51 and 34, were detained by gardaí over the killing of David Black in a gun attack on the M1 motorway in Antrim last year.
The prison officer, a father of two, was shot dead as he drove from his home in Cookstown, Co Tyrone to Maghaberry Prison just outside Lisburn.
Gardaí said they arrested two men as part of investigations into dissident republican activities and the murder.
A number of searches were carried out in the Leitrim and Cavan areas.
The two men are being held in the Cavan area.
They can be detained for up to 72 hours.
