A man has appeared in a Dublin court after being charged with the murder of a former Sinn Fein official who was shot dead 20 years ago.
Denis Donaldson, 55, was killed at a remote cottage in County Donegal in April 2006, months after admitting his role as a police and MI5 agent for two decades.
Antoin Duffy, who is in his 40s and of no fixed address, has been charged with the murder of Mr Donaldson at Cloghercor, Doochary.
He has also been charged with the attempted murder of a second man in County Donegal in November 2007.
Duffy appeared before the Special Criminal Court in Dublin on Monday afternoon.
Earlier he was arrested by Irish police after arriving at Casement Aerodrome in Baldonnel, on the western outskirts of the city, following his extradition from Scotland on a European Arrest Warrant.
