Ukraine has banned a Russian singer from entering the country to compete at the Eurovision Song Contest, Reuters reports.

Russian singer and composer Yuliya Samoilova has been barred from entering the country for the next three years, over a past performance in  Crimea.

“The Security Service of Ukraine has banned Yuliya Samoilova from entry for three years,” Ukrainian security services (SBU) said on Wednesday.

The SBU has blacklisted at least 140 other Russian artists.

Ukraine is due to host the Eurovision Song Contest in its capital Kiev, in May.
