Glastonbury bosses have said they are "appalled" by comments made by rap duo Bob Vylan during their performance at the festival Saturday.

Organizers of the Glastonbury Festival said Sunday they are "appalled" by the onstage statements of the punk duo Bob Vylan, whose singer led the crowd in a series of chants including "Death, death to the IDF" and "Free Palestine" the day before.

Punk duo Bob Vylan appeared on Saturday (June 28) before Kneecap on the West Holts stage. During their set, they instigated chants of “Free Palestine” and “Death to the IDF,” in reference to the Israel Defense Forces, and displayed messages criticising the BBC, the festival’s official media partner.
