KIEV (Reuters) - This year's Eurovision Song Contest host Ukraine may ban Russia's competitor from entering the country following reports the singer has visited Crimea since the peninsula was seized by Russia, Ukraine's state security service (SBU) said on Monday.

Russia's annexation of Crimea in 2014 sent relations with Ukraine to an all-time low and now even sporting or cultural events are potential sources of tension between the two.
