Several Scotland fans were injured after being set upon by a gang of local hooligans in Ukraine. Up to 300 local youths launched an "unprovoked" attack on members of the Tartan Army in Kiev.
The trouble broke out last night in the city's Independence Square, ahead of tonight's Euro 2008 qualifying match.
The Scottish Football Association said several Scots suffered broken bones and cuts. The exact number of supporters involved is unknown.
Approximately 3,000 Scottish fans are in Kiev for the match. The SFA has praised the response of the Scotland fans who faced the trouble.
Derek Kirkwood, security adviser to the SFA said: "The Scotland fans were absolutely magnificent, in that they did not react to the violence or provocation.
"They chose to walk away from the scene rather than get involved, and their behaviour was exemplary."
But the footballing authority has warned Scottish fans in the country to remain on their guard.
The SFA said: "Following the incident, which was entirely unexpected, the SFA have advised fans to be careful in the city and to avoid any possible further provocation."
A spokesman for the British Embassy in Kiev said he had heard about trouble in Independence Square, but did not know how many people were involved. He was he was not aware of anyone who needed hospital treatment.
Scotland currently sit at the top of their Euro 2008 qualifying group after beating France 1-0 in Glasgow at the weekend. PA
