JUSTICE campaigners vowed to fight on after the release of key documents regarding British state collusion in the deadliest killing of the Troubles was blocked by a Belfast court today.

A High Court judge ordered a U-turn on a December decision to disclose documents relating to the Monaghan/Dublin bombings of May 17 1974 – the deadliest single day of the Troubles, in which 34 people were killed.

Survivors and the bereaved are suing over the alleged involvement of British soldiers and the police, who they claim aided a notorious loyalist paramilitary gang to carry out three bombings in the Dublin rush hour and another in Monaghan 90 minutes later.
