In Paris, young people tried to have a big party in a park last night. The police found out and ended the party.
It was quite intense. The agents were hit by fireworks and bottles. The police used tear gas to scare everyone. Nine policemen were injured.
Young people asked social media to come to the park. They did this under the hashtag Project X. This is a 2012 film about a big party that is getting out of hand.
