Bosnia's international high representative on Friday accused the country's Serb statelet's political leadership of seeking to destabilise the Balkan nation, and urged an end to actions that threaten to "undermine" its peace accords.

Bosnia's Serb political leader Milorad Dodik was sentenced to one year in prison and banned from holding public office for defying the decision of the fragile country's international peace representative.

The Kremlin said on Thursday it believed a one-year jail term and political ban handed down to Bosnian Serb separatist leader Milorad Dodik was politically-motivated and could have negative and destabilising consequences for the Balkans.
