Kosovo special police units on Saturday prevented a train painted in Serbia's national colors and bearing the words "Kosovo is Serbia" from crossing the border, Reuters said.

Serbia does not recognize the independence of Kosovo, its former province, and did not seek Pristina's permission for the passage of the train, which it paid for and organized. On Sunday Serbia's president, Tomislav Nikolic, said Kosovo's action had shown it wanted war with Belgrade.

"Serbia’s intention is to use this train, which was donated by Russia, first to help carve away the northern part of Kosovo and then ... attach it to Serbia. It is the Crimea model," Thaci said in an interview.

Crimea's ethnic Russians welcomed Moscow's annexation – carried out initially by soldiers wearing unmarked uniforms to disguise their identity – though the move also triggered Western economic sanctions against Russia.
