Bosnia tension eases as Serbs cancel referendum, BBC (2011)
The article explains that the Bosnian Serb leader has cancelled a referendum that would have gauged support for the presence of a UN envoy that is accused, along with Bosnia's war crimes court, of having a bias against Serbs. The referendum would have also "asked Bosnian Serbs if they supported Bosnia's central institutions, which tackle war crimes cases, corruption and organised crime." After assurances from high ranking EU officials that the system would be reviewed, the referendum was cancelled. The tension between the country's two ethnic groups remains.
