Kolinda Grabar-Kitarović

"We are eagerly awaiting Putin in Zagreb," she said in an interview with the Moscow-based Kommersant, recalling that Putin was already invited last year during her trip to Sochi, and once again this summer while she was in Moscow.

Rivlin and Kolinda Grabar-Kitarovic on Wednesday visited the grounds of the former death camp for Serbs, Jews, and Roma, that was set up and operated during the Second World War by the Ustasha regime of the Independent State of Croatia (NDH), a Nazi-allied entity.

Vucic said this when asked by reporters to comment on Croatian President Kolinda Grabar-Kitarevic's statement about Croatia and Albania being "brothers in arms."

Vucic said it "speaks sufficiently to the difficulty of our position and how much some people don't want us to progress."

Ahead of Wednesday's World Cup semi-final showdown in Moscow, British tabloids have cranked up their coverage of England's Western Balkan rival in the match, Croatia.

Kolinda Grabar Kitarovic has said that "the will of the people must be respected" after a conservative campaign group called The People Decide gathered more than 370,000 signatures, equal to 10 per cent of the total electorate - enough to have its referendum proposal considered by officials.

This has been reported by the daily Vecernje Novosti, which added that Serbia will in this way respond to the attempts to relativize the crimes of the Ustasha regime of the Independent State of Croatia (NDH).

Dacic said that the list of victims will be sent to Zagreb by registered mail.

Dacic also stressed that Belgrade will respond in kind if Zagreb decides to withdraw its ambassador.

And that would be "a column of unity," she said.

In addition, Grabar-Kitarovic stands for "determining the truth about what actually happened" in Jasenovac - this time "using modern methods."

The Ustasha regime, in power in the Nazi-allied Independent State of Croatia (NDH), established and operated Jasenovac as the biggest of its death camps for Serbs, Jews, and Roma.

"First of all, it should be clearly stated that the gathering that is held is a church manifestation. It is not up to the government, the president of the province nor the provincial government to decide whether this gathering will be held," Kurz told reporters.

Croatian President Kolinda Grabar-Kitarović will be on an official visit to Bulgaria today at the invitation of the head of state Rumen Radev, the Presidential press secretary announced.
