This is the moment an Irish folk band had their microphones cut after they started a pro-Palestine chant at a music festival.

The Mary Wallopers were performing at the Vicorious Festival in Portsmouth on Friday when they claimed they were 'cut off' for displaying a Palestinian flag on stage.

The music group shared a video on Instagram on Saturday, in which they are shown entering the stage while brandishing a Palestinian flag.

'Free Palestine and f***k Israel', the lead singer shouts as he greets the crowd before the band start to play.

A Victorious crew member then appears in the shot and can be seen talking to a female band member, but the music group continues to play.
