Another UK band has come under fire for its “threatening” comments against Israel’s ongoing war in Gaza — stirring up a frenzy at an outdoor music festival Saturday. English-based punk duo Bob Vylan whipped the crowd at England’s annual Glastonbury Music Festival into a furor, and led the massive audience in gang chants of “Free, free Palestine” and “Death, death to the IDF” in referencing the Israeli Defense Forces. Police are said to be investigating the band’s performance, Deadline reported.
