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.

The US State Department has revoked the visas of members of Bob Vylan, a British rap punk group who led crowds to chant “death” against Israel’s military at a UK music festival this past weekend.
