PARIS: France on Thursday faces its first major security challenge of the Euro 2016 football championships with a giant open-air concert at the 90,000-capacity fan zone in Paris. Superstar French DJ David Guetta will play for the crowd at the foot of the Eiffel Tower in Paris, a day before hosts France face Romania in the tournament’s opening match at Paris’ Stade de France. The stadium was targeted by suicide bombers in the November 13 attacks that killed 130 people across the capital and there are fears that Europe’s four-yearly football extravaganza could be targeted. Unresolved strikes over labor reform have provided another unwelcome distraction to the showpiece event, with Paris scrambling to stop rubbish piling up in its streets. German defender Jerome Boateng became the first high-profile player to say he was banning his family from visiting stadiums during the tournament because he was concerned for their safety.
