Ivan Penava

Kolinda Grabar Kitarovic said on Thursday that she supports Vukovar's mayor, Ivan Penava, who has claimed that the extension of Serb minority rights in the town would harm ethnic relations - despite a Constitutional Court ruling saying this must be done soon.

Serbia has protested after Vukovar town council on Monday said that signs in Cyrillic, the script of the Serbian minority in Croatia, will no longer be displayed on town institutions, squares and streets.

The receipt of any official note in Cyrillic in Vukovar will also now require a special request and payment of a fee of three euros.
