The rally in Nikola Pasic square was organised by several associations of Croatian Serb refugees. In attendance were about 250 refugees and families of those killed in Storm.
The resolution that was read out also demanded that "Croatia publish the truth about 'Storm' for the purpose of lasting peace, reconciliation and coexistence".
According to the document, 1,960 Serbs were killed or went missing in the 1995 operation and more than 200,000 were exiled. "In the continuation of the military operation, on the territory of the internationally recognised Bosnia and Herzegovina, in Bosanska Krajina, 655 Serbs were killed and 125,000 were exiled, mainly civilians," it said.
"We demand that the violence against life be officially proclaimed genocide also at the Hague tribunal and that the killing of all civilians be condemned," said the resolution.
Croatia is further demanded to regulate the pension, tenancy and other rights of refugee and displaced Serbs.
During a protest march and at the rally some people carried a large banner saying "Crime Without Punishment, With 'Storm' to the NDH", the acronym referring to the Nazi-styled 1941-45 Independent State of Croatia. Writings above the stage where the resolution was read out said "Krajina inhabitants are victims of genocide" and "'Storm' is still on".
Those gathered dispersed peacefully. The rally and the march had tight police security.
In the morning a memorial service for the victims of Storm was held in St. Mark's Church. In attendance were Serbian President Boris Tadic, Prime Minister Vojislav Kostunica and nearly the entire government.
Speaking on the occasion of the anniversary, Tadic said the pogrom against Serbs must never be forgotten, with the constant reminding that all those who committed crimes must be brought to justice.
"For a better future, both Croatia and Serbia must resolve the issue of displaced Serbs more effectively," said Tadic, adding this was the priority task of Croatia's President Stjepan Mesic and Prime Minister Ivo Sanader as well as his and Kostunica's.
Tadic said Serb returnees must be provided security, the right to employment and all rights enabling them to live and work as equal citizens of Croatia.
