By Sachin Ravikumar and Muvija M LONDON (Reuters) -British police on Monday launched a criminal investigation into musical duo Bob Vylan and Irish rap band Kneecap's gigs at the Glastonbury music festival after they led chanting against the Israeli military and Prime Minister Keir Starmer.

During Bob Vylan’s set, the band’s singer Bobby Vylan (born Pascal Robinson-Foster) led Glastonbury crowds in chants of both “free, free Palestine” and, more controversially, “death, death to the IDF.”
