The prime minister is involved; so is the U.S. deputy secretary of State. The BBC is changing policies. But Bob Vylan remains steadfast.

The BBC issued a formal apology after broadcasting a controversial performance from the rap-punk group Bob Vylan at England's Glastonbury festival. Bob Vylan — outspoken critics of Israel's war on Gaza — led its crowd at last weekend's festival in a chant of "Death to the IDF," or Israel Defense Forces.

BBC apologizes after streaming Bob Vylan's controversial Glastonbury set despite 'high risk' warning. New policies ban live broadcasts of risky acts.
