A man who lost his sister in the Shankill bombing has condemned the pro-IRA chanting that broke out at Belfast's Féile an Phobail finale.
Gary Murray said the lyrics sang at the Wolfe Tones gig on Sunday night had "caused untold hurt and upset to victims of the IRA".
TUV leader Jim Allister also said that the gig in the Falls Park in west Belfast had "degenerated into a terror fest".
It comes after video footage emerged of crowds chanting 'Ooh, ah, up the 'RA' at the show on Sunday night.
Last year's festival also saw similar scenes of singing in support of the IRA at the Wolfe Tones concert.

Mr Murray, whose sister Leanne (13) was killed in the 1993 bombing of Frizzell's on the Shankill Road, said it had caused hurt to the families of those killed by the IRA.
In a statement issued through Jamie Bryson’s JWB Consultancy firm, Mr Murray also criticised the Charity Commission for Northern Ireland after he had lodged an official grievance with the watchdog and PSNI following last year’s event.
"This was not only via the Wolfe Tones, but also a band known as 'Shebeen' who expressly sang a number of songs celebrating the IRA murder of British soldiers and other innocent victims,” he said.
"This, as with every year, has caused untold hurt and upset to victims of the IRA."

Mr Allister also criticised the Charity Commission for failing to take action over pro-IRA chants in previous years.
“Once more the west Belfast festival degenerated into a terror fest with its ‘Up the Ra’ finale," he said.
“The fact that shamefully the Charity Commission failed to act against such glorification of terror under the auspices of an organisation it continues to accept as a bona fide charity, guaranteed this deliberate insult to IRA victims.
“When the Charity Commission by its inaction sanctions such, rest assured there will be plenty of IRA acolytes ready to pay homage to the murdering provos as a new generation is indoctrinated into the bloodthirsty cult of worshipping at the shrine of IRA terror.
“The fact that this festival continues to be lavishly funded from the public purse adds to the hurt and insult endured by the victims of terrorism.”
The Charity Commission said in a statement: "In August of last year, the Charity Commission for Northern Ireland received concerns regarding the annual West Belfast Festival held by registered charity, Féile An Phobail Limited.
"Having assessed the concerns raised, commissioners concluded that the charity, as a result of performances at the festival, had not contravened charity law.
"One of the concerned parties requested that the commission review its decision not to take regulatory action under its internal decision review process.
"The charity was advised of this request.
"The concerned party also requested that a specific question is referred to the Charity Tribunal under para. 1 of Schedule 4 to the Charities Act (Northern Ireland) 2008.
"The concerned party has been advised that this request is currently being considered by the Commission.
"While both requests are under consideration, it would be inappropriate to comment any further at this time."
The director of Féile An Phobail said this year's event had drawn record crowds and the festival "includes all opinions and provides a platform for many different views".
Kevin Gamble said a record 120,000 people had attended events at this year's festival.
He added: "Over the last 35 years, Feile has a proven track record of delivering significant social, cultural and economic benefits to the city of Belfast, and this increases year on year.
"This year, representatives from all communities were welcomed to Feile to have their voice heard, both as spectators and participants.
"All political persuasions attended and participated in various panel discussions, as did representatives from minority ethnic communities and international visitors.
"Féile an Phobail includes all opinions and provides a platform for many different views."
