The trial of five Catholic Worker peace activists collapsed today at the Dublin Circuit Criminal Court as Judge Frank O'Donnell discharged the jury.

The five had been charged with causing criminal damage to a US Navy warplane at Shannon Airport on 3 February 2003.

Discharging the jury, the judge said he could not reveal the reason for the move because he had to ensure that the retrial was fair.

The Director of Public Prosecutions must now decide whether to prosecute the five, who have been on strict bail conditions for over two years.
