Host of the Euro 2016 tournament this summer, France surrounded its largest soccer stadium with a 7-foot fence and deployed 1,700 security personnel in a bid to prevent repeats of November's ISIS bombing. However, this did not all go to plan as the test run caused chaos.
The new measures were installed at the Stade de France ahead of Euro 2016 which kicks off across the country in three weeks (the first match of Euro 2016 is scheduled for June 10).
However, thousands of fans became trapped by a new two-tier security system that forced supporters to pass through pat-downs and multiple ticket checks on Saturday. Some people in the densely-packed crowds even ignited fireworks in protest to the measures.
Poor signage "left 40,000 fans scattered around" the stadium, Italy's Gazzetta World newspaper reported. It added that some supporters were "led into narrow tunnels" as they tried to enter one of just four entrances into the security perimeter.
