While Croatia celebrates 25 years of the police-military 'Storm' operation which re-took control of the territories held by rebel Serbs for four years, since the start of the war in 1991, Serbia mourns the victims during and after the operation ended.
Serbia's Deputy Prime Minister Zoran Mihajlovic said that the different mood in two countries "should not discourage us to, for the sake of the future, go toward rapprochement, better neighbouring cooperation and try to resolve open issues."
She added the Serbs would never forget their victims, but that it was important for both Serbia and Croatia "to look for ways different from those in the past and that, as the neighbours, build good relations."
"(Croatia) will celebrate the operation of ethnic cleansing of our people during which most of the victims were civilians, older people, women and children. This brutal crime in the middle of Europe remains a crime without punishment. The time hasn't brought justice to the victims, and it will remain a shameful page in the book of the European history," Nebojsa Stefanovic, Serbia's Interior Minister said.
Serbia's Humanitarian Law Centre called for justice for the victims and the responsibility of both sides.
"While in Croatia the anniversaries of the 'Storm' operation are celebrated, ignoring the crimes during and after it, the state commemorations in Serbia abuse the victims for political purposes," HLC said in a statement.
Serbia's opposition Party of Freedom and Justice (SSP) accused President Aleksandar Vucic of manipulating with people on the occasion of 'Storm.'
SSP said that political representatives of the Serbs in Croatia should not allow "the same people from Belgrade who berry the historical responsibility for the fate of the Serbs in Croatia" lead their politics.
Later on Tuesday, Savo Strbac, a Croatian Serb and the head of the documentation centre Veritas, commented the decision by Boris Milosevic, a leader of Croatian Serbs and a deputy Prime Minister in the Croatian new Government: "I cannot support a Serb going to Knin to celebrate the criminal operation, an ethnic cleansing which is confirmed as such by international courts."
He said he would go to Knin if that would contribute to the reconciliation of the Croats and Serbs and better relations between Croatia and Serbia.
