The Serb leader, Serbian Deputy Prime Minister Bozidar Djelic and Foreign Minister Vuk Jeremic have been severely criticized by opposition parties for seemingly reconciling themselves to the loss of Kosovo in exchange for guarantees from the EU following the signing of a Stabilization and Association Agreement (SAA) last week.
"We will file a criminal case on behalf of the [Serbian] people against those who threatened the territorial integrity and the sovereignty of our state by signing the SAA agreement and, therefore, committing...an act of state treason," President of the Serb National Council of Northern Kosovo Milan Ivanovic told a news conference in Belgrade.
The accusations come amid deep divisions between pro-Western reformers and nationalists before the May 11 early parliamentary elections.
Nationalist Serb Prime Minister Vojislav Kostunica has already spoken out against the EU agreement and said the new government will annul the move once it wins the elections.
Kosovo, with a 90% ethnic-Albanian majority, has been formally recognized as a sovereign state by over 35 countries including the U.S. and most EU members since it proclaimed its independence from Serbia on February 17. Russia and China continue to back Belgrade's position that Kosovo will always remain a part of Serbia.
