No Russian act will participate in this year's Eurovision Song Contest, the organisers have announced.
The executive board of the European Broadcasting Union (EBU), of which Ireland is a member, says it made the decision following a recommendation on Friday by the contest's governing body.
It says this recommendation was "based on the rules of the event and the values of the EBU."
The move was also supported by the EBU's Television Committee.
In a statement, the EBU says: "The decision reflects concern that, in light of the unprecedented crisis in Ukraine, the inclusion of a Russian entry in this year's contest would bring the competition into disrepute.
"Before making this decision the EBU took time to consult widely among its membership."
The EBU adds that it is an apolitical organisation "committed to upholding the values of public service."
"We remain dedicated to protecting the values of a cultural competition which promotes international exchange and understanding, brings audiences together, celebrates diversity through music and unites Europe on one stage", it says.
Brooke Scullion will represent Ireland at this year's competition in the second semi-final in Turin, Italy.
Ireland famously won four out of five contests in the 1990s, and became the first country to win three times in a row.
Ireland has won the Eurovision a record seven times in total - having only missed the contest in 1983 and 2002.
