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’s Glastonbury performance has led to a police assessment and condemnation from festival organisers and the BBC. The duo led crowds at the West Holts Stage in a chant of “death, death to the IDF” as they performed before Irish rap trio Kneecap.
