Ashley Barnes and Chris Wood scored second-half goals to win against West Ham at a toxic London Stadium.
Barnes broke the deadlock with a fine shot into the top corner on 66 minutes after having an earlier effort harshly ruled out for offside. Wood then doubled Burnley's lead moments after coming on as a sub, before Barnes struck again.
West Ham fans had earlier protested against the club's owners with banners and they expressed their anger in more militant fashion late in the game by flooding onto the pitch.
