'Columbia Three' campaigners travelling to Bogota

Campaigners for three Irishmen being held in Colombia are travelling to Bogota this weekend to mark the first anniversary of their imprisonment.

Niall Connolly, James Monaghan and Martin McAuley are due to go on trial in October charged with using false documentation and training of FARC guerrilla rebels.

The three could face 20 years in jail if they are convicted.
