PARIS (AP) Croatia fans have a habit of disrupting and delaying matches at the European Championship.
On Friday, they added another ugly chapter to that history during Croatia's 2-2 draw with the Czech Republic.
Firecrackers exploded on the field in Saint-Etienne and burning flares rained on the turf, spewing smoke across the stadium - just as they did at all three Croatia matches at Euro 2012. The referee, Mark Clattenburg, stopped the game briefly.
Exactly why it happened, which provoked clashes among Croatia fans themselves, was not immediately clear. UEFA said it will hold open disciplinary procedures against Croatia following the incidents.
