Two British soldiers have been granted the right to give their evidence at the Bloody Sunday tribunal behind a screen.
Chairman of the inquiry, Lord Saville, said if they were seen giving evidence it would be a breach of their human rights.
All soldiers due to give evidence to the inquiry when it moves to London in September have been granted anonymity.
But today's decision means the two soldiers will only be visible to members of the tribunal, lawyers and Ministry of Defence officials.
