The Glastonbury Festival’s official response to chants of “Death to the IDF” and “From the river to the sea” from the stage this weekend was slammed Sunday by the Simon Wiesenthal Center, with the Jewish advocacy group’s CEO calling the statement “bland,” “cowardice” and “complicity.”

The rap duo have come under fire for encouraging audiences at the U.K. music festival to join in on shouting "death to the IDF" during their set.

British police are weighing an investigation after musicians Bob Vylan and Kneecap made anti-Israeli comments onstage at Glastonbury Festival.
