Iceland has joined Spain, Ireland, Slovenia and the Netherlands in saying it will boycott the 2026 Eurovision Song Contest.
All five countries have withdrawn after Israel's participation in the competition was officially confirmed last week.
Stefan Eiriksson, director-general of Icelandic national broadcaster RÚV, said: "There is no peace or joy connected to this contest as things stand now. On that basis, first and foremost, we are stepping back while the situation is as it is."
RÚV said Israel's participation had "created disunity among both members of the European Broadcasting Union (EBU) and the general public".
The broadcaster's board agreed the decision at a meeting on Wednesday, hours before the deadline for countries to confirm whether they will join what's supposed to be a celebratory 70th anniversary edition of the song contest next May.
Iceland was believed to be the last remaining country to announce its decision.
Eurovision director Martin Green said: "We respect the decision of all broadcasters who have chosen not to participate in next year's Eurovision Song Contest and hope to welcome them back soon."
Israel's presence at Eurovision has been an increasing source of tension, because of the war in Gaza and concerns about the voting and campaigning processes, including accusations that Israel's government tried to influence the public vote at this year's event.
A new raft of measures designed to protect the integrity of the vote was approved at an EBU summit last week, after which most countries confirmed they would travel to Vienna for the 2026 contest.
The Icelandic broadcaster's board had previously approved a recommendation to ask the EBU to ban Israel from Eurovision 2026.
Iceland was reportedly among seven countries that then requsted a vote at the EBU general meeting on Israel's participation.
That request was denied, and Israel's future participation was instead effectively tied to a ballot on the new voting and campaigning rules.
The Icelandic broadcaster said that while the new measures addressed many of its concerns, it "believes that there are still doubts whether the agreed adjustments would be fully satisfactory".
"RÚV has repeadly raised concerns that various Icelandic stakeholders, such as artist associations and the general public, were opposed to participation in the contest.
"Furthermore, RÚV had requested the EBU to exclude [Israeli public broadcaster] KAN from the contest in accordance to precedents.
"It is a complex matter which has already damaged the contest's reputation and EBU, emphasizing the necessity of a solution for all concerned parties."
According to a transcript of Thursday's meeting supplied by KAN, the broadcaster's chief executive Golan Yochpaz criticised those trying to get Israel thrown out.
"The attempt to remove KAN from the contest can only be understood as a cultural boycott," he said. "A boycott may begin today with Israel, but no one knows where it will end or who else it may harm.
"Is this what we truly want this contest to be remembered for on its 70th anniversary?"
Israel has taken part in Eurovision since 1973 because KAN, its public broadcaster, is a member of the EBU, which organises the competition.
Israel has won four times, most recently in 2018, and came second in the 2025 contest.
Iceland has never won but came second in 1999 and 2009.
