A parachutist caused debris to fall on to the pitch as well as into the stands as he flew into the wires that hold up the spider camera that hovers above the playing surface, with some of it nearly striking France manager Didier Deschamps.
The protester ended up on the pitch just after kick-off, with German star Antonio Rudiger making his way over to see if he was okay after a heavy landing.
Once the full-time whistle had blown on a crucial 1-0 victory for Les Bleus over Joachim Löw’s Germany side in Munich, Greenpeace released a short statement.
The organisation said “We sincerely apologise to the two people injured and to fans and players alike”, the protester donned a parachute that had both “KICK OUT OIL!” and “Greenpeace” written across it.
They explained that a soft ball was intended to be dropped with a message for German automaker Volkswagen on it, but the stunt went awry after the parachute was caught up in the camera wires.
Their statement went on: “The paraglider was supposed to go over the stadium and let a soft ball float down to the pitch with a protest message to EURO 2020 sponsor Volkswagen.
“We are calling on it to put an end-date to the production of climate damaging internal combustion engine cars and transition to EVs faster.
“Technical difficulties forced the pilot to an emergency landing in the stadium.”
Greenpeace concluded by promising it would “do everything we can to clear up the cause for this.”
The tournament’s governing body, UEFA, vowed that “law authorities will take the necessary action” after they deemed the stunt “reckless and dangerous”.
The European Football organisations full statement read: “Shortly before the start of tonight’s UEFA EURO 2020 match between France and Germany in Munich, a protester briefly entered the stadium from the air and tried to land on the pitch.
“This inconsiderate act – which could have had very serious consequences for a huge number of people attending – caused injuries to several people attending the game who are now in hospital and law authorities will take the necessary action.
“UEFA and its partners are fully committed to a sustainable EURO 2020 tournament and many initiatives have been implemented to offset carbon emissions.
“The staging of the match was fortunately not impacted by such a reckless and dangerous action, but several people were injured nonetheless.”
Jens Grittner, spokesman for the German national team echoed UEFA’s sentiments by condemning the actions of the protestor.
“We as the German football federation condemn it of course, because it wasn’t just him, but others that he endangered and injured. It’s unacceptable from our point of view and the incident is being checked by the police, the authorities here in Munich and at UEFA.
“But of course we also condemn what happened there. It could probably have turned out much worse.”
