The U.S. State Department on Monday revoked visas issued to British punk-rap duo Bob Vylan after a member of the group led hateful chants against Israel during a performance at the Glastonbury music festival.

The group had been set to kick off a 20-show tour in the U.S. in late October, but now the State Department says the duo is not welcome in the U.S. after the rap duo’s lead vocalist, Bobby Vylan, led chants of “death, death to the IDF,” referring to the Israel Defense Forces, and “From the river to the sea, Palestine must be, will be, inshallah, it will be free.” The latter phrase is seen as a call for Israel’s destruction and a denial of its right to exist.

“The State Department has revoked the US visas for the members of the Bob Vylan band in light of their hateful tirade at Glastonbury, including leading the crowd in death chants,” Deputy Secretary of State Christopher Landau said in a post on X on Monday.

“Foreigners who glorify violence and hatred are not welcome visitors to our country.”

Meanwhile, local police in Britain say they are investigating Bob Vylan’s performance, alongside the performance of Irish rap band Kneecap over public order incidents.

A member of Kneecap urged fans to “start a riot” at his bandmate’s upcoming court appearance related to a terrorism charge. A member of the band also said “f*** Keir Starmer” on stage. Starmer had called for the band to be excluded from the festival.

The BBC landed in hot water after it aired a livestream of the controversial Bob Vylan performance. The network said Monday it regrets having aired the performance.

The BBC issued an on-screen warning for strong and discriminatory language while the set was streamed online, but on Monday said it should have cut the stream altogether after receiving widespread backlash, including from British Prime Minister Keir Starmer and media regulator Ofcom.

“The antisemitic sentiments expressed by Bob Vylan were utterly unacceptable and have no place on our airwaves,” the BBC said in a statement.

“The team was dealing with a live situation, but with hindsight, we should have pulled the stream during the performance,” the BBC added. “We regret this did not happen.”

Vylan, for his part, defended his comments in a post on Instagram.

“I said what I said,” he wrote, and added that he had been “inundated with messages of both support and hatred”.
