The stewards who failed to stop a pitch invasion by members of the Pussy Riot protest group at the World Cup final between France and Croatia will face disciplinary action, tournament organisers said on Friday.

Four protesters wearing fake police uniforms ran onto the pitch at Moscow’s Luzhniki stadium on Sunday, causing play to stop briefly at the match, which was attended by President Vladimir Putin and other senior officials.
