BELGRADE (Sputnik) – The train left Belgrade for Mitrovice was stopped in the city of Raska near the border with the partially recognized republic of Kosovo, the Beta news agency reported.
Earlier on Saturday, videos emerged on the Internet that unknown people rigged the railway with explosives.
The train was coloured as the Serbian flag with the caption "Kosovo is Serbia" being written in 21 languages on it.
The Kosovar authorities are opposing railway communication between Serbia and Mitrovice saying that it is a threat to the Kosovo’s sovereignty.
Serbia does not recognize Kosovo as an independent state, which was unilaterally proclaimed in 2008. Kosovo is recognized by over 100 UN member states.
