Protestors have gathered this afternoon at the Free Derry Museum in Derry's Bogside.
The group are angry at the inclusion of RUC and British Army dead in a list of victims of the Troubles.
Management say the video reel in the exhibition is purely a factual listing and not a commemoration.
However the demonstrators do not agree and claim it is inappropriate.
Kate Nash, whose brother William was killed on Bloody Sunday, says it is a memorial.
"It is most definitely a memorial. They keep denying that: 'It's a list, it's a list,' that's all we hear, but it's not. It's a memorial and it's inappropriate to have it in the people's museum in the Bogside."
