Glastonbury (United Kingdom) (AFP) – A British punk-rap group faced growing criticism on Sunday for making anti-Israel remarks at the Glastonbury music festival that have sparked a police inquiry.

Bob Vylan led crowds in chants of “Death, death to the IDF”, a reference to the acronym for the Israeli military, during their set on Saturday.

British police officers are also examining comments by the Irish rap trio Kneecap, whose members have likewise been highly critical of Israel and its military campaign against the Palestinian militant group Hamas in the Gaza Strip.

One of Kneecap’s members wore a T-shirt dedicated to the Palestine Action Group, which is about to be banned under UK terror laws.

The UK government has “strongly condemned” Bob Vylan’s chants, which festival organisers said had “very much crossed a line”.

“We are urgently reminding everyone involved in the production of the festival that there is no place at Glastonbury for antisemitism, hate speech or incitement to violence,” the festival said in a statement.

Avon and Somerset police said Saturday that video evidence would be assessed by officers “to determine whether any offences may have been committed that would require a criminal investigation”.

The chants about Israel’s military, condemned by the Israeli embassy in London, were led by Bob Vylan’s frontman Bobby Vylan.

They were broadcast live on the BBC, which airs coverage of Britain’s most popular music festival.

“I thought it’s appalling, to be honest,” Wes Streeting, the Labour’s government’s health secretary, said of the chants, adding that “all life is sacred”.

“I think the BBC and Glastonbury have got questions to answer about how we saw such a spectacle on our screens,” he told Sky News.

The Israel embassy said in a statement late Saturday that "it was “deeply disturbed by the inflammatory and hateful rhetoric expressed on stage at the Glastonbury Festival”.

But Streeting also took aim at the embassy, telling it to “get your own house in order”.

“I think there’s a serious point there by the Israeli embassy. I wish they’d take the violence of their own citizens towards Palestinians more seriously,” he said, citing Israeli settler violence in the West Bank.

A spokesperson for the BBC said Vylan’s comments were “deeply offensive” and the broadcaster had “no plans” to make the performance available on its on-demand service.

Festival-goer Joe McCabe, 31, told AFP that while he did not necessarily agree with Vylan’s statement, “I certainly think the message of questioning what’s going on there (in Gaza) is right.”
