"We deeply regret that such offensive and deplorable behaviour appeared on the BBC," the broadcaster said in a new statement

After punk duo Bob Vylan chanted "death to the IDF" live on air, the BBC has vowed to take action to "ensure proper accountability" for those found to be responsible for the broadcast.

Britain's national broadcaster said on Thursday it would no longer broadcast or stream live any music gig deemed "high risk" after it was widely criticised for showing punk-rap duo Bob Vylan chanting against the Israeli military at Glastonbury.
