People leaving Shannon Airport and others at check-in desks were attacked by a group of armed men and women who forced them back into the terminal and held them hostage.

John Carthy's sister, Marie, is questioning why the Garda Emergency Response Unit didn't use non-lethal equipment in their possession to resolve the armed siege, which ended in the shooting dead of her brother in April 2000.

The High Court is due to fix a date for a judicial hearing on a challenge brought about by members of the Gardai against the Oireachtas committee inquest into the Abbeylara shooting.

The Garda Commissioner has refused to tell the Abbeylara inquiry why a third shot was fired at John Carthy when he appeared to be falling.
