NORTHERN Ireland's Public Prosecution Service has announced no further former soldiers will be prosecuted over their actions on Bloody Sunday.

Thirteen unarmed civilians were fatally shot when troops of the 1st Battalion of the Parachute Regiment fired on demonstrators during a civil rights march in Derry on January 30, 1972. A further 15 people were injured. 

Last year, prosecutors decided no charges should be brought against 15 veterans over the massacre. That decision has now been upheld upon review.

One man, Soldier F, remains the sole individual facing court.

John Kelly, whose brother Michael was killed that day, said he was disappointed.

"We're not giving up yet, we have now the next stage, the judicial review at the High Court," he said.

"It's been a long road, up to nearly 50 years, we're all getting old, a lot of people are dying but as long as we're able to walk, we'll go after them and we certainly will not stop until we see justice for our loved ones."

Sinn Fein MLA Martina Anderson also expressed disappointment at the PPS decision not to prosecute more former soldiers over Bloody Sunday.

"This is another deeply disappointing day for the Bloody Sunday families," she said.

"We share that disappointment given the well-documented actions of the British Army on Bloody Sunday.

"I want to pay tribute to the Bloody Sunday families for their strength and determination for over 48 years in their ongoing campaign for truth and justice."

DUP MP Gregory Campbell said the decision of the PPS is "not surprising".

"The issue now will be, is there now going to be a judicial review which is going to entail further cost - remember there's already been almost £200 million spent on the public inquiry, the most expensive in legal history in the UK," he told the BBC.

"Is there going to now be a judicial review, is that going to mean further trauma and delay for all of those involved, and what is the outcome going to be?

"Really, I think more and more people will be saying how much further is this going to go on, because there are families today across Northern Ireland who are still grieving? There are families of two police officers who were murdered in the area where the Bloody Sunday events happened, just three days before. They have never received justice, never received a public inquiry and never received any independent review into the circumstances surroundings the murders of their loved ones."
