British police have launched a criminal investigation into a performance by rap-punk duo Bob Vylan at the Glastonbury Festival on Saturday, when the group led chants of “death to the IDF,” or Israel Defense Forces.

Members of the British rap punk duo Bob Vylan had their visas revoked by the US and are under investigation by local police after leading a crowd to chant “death” to Israel’s military at a UK music festival this past weekend.

The controversy comes as the war in Gaza between Israel and Hamas rages on. It erupted in October 2023 when Hamas attacked Israel and killed some 1,200 people and abducted another 251, Israeli officials say. Israel's offensive in the devastated territory has killed over 55,000 people, according to health officials in the Hamas-run territory.
