Meanwhile, Kneecap, who are vocal critics of Israel’s military action in Gaza, during their performance criticised Israel — accusing it of genocide, an allegation denied by Israel’s government.

The band Kneecap attracted headlines when their rapper, Liam Óg Ó hAnnaidh, known as Mo Chara, faced terrorism charges for allegedly displaying a Hezbollah flag, a recognized terrorist symbol, at a past concert.

In a Guardian interview, Chara was asked if he regretted his actions and other remarks captured on video, to which he responded: “Why should I regret it? It was a joke — we’re playing characters.”

“I think they have obviously gone a bit close to the mark sometimes but if you are an Irish person living in Ireland you’ve lived a hundred years of oppression in Northern Ireland, so why can’t you say what you feel is right?” another fan said.

“The prime minister of your country, not mine, said he didn’t want us to play, so f*** Keir Starmer,” Chara told the crowd.
