Paris ( CNN ) -- Seventeen police officers were injured in violent clashes with young people in the city of Amiens in northern France overnight , Interior Minister Manuel Valls said Tuesday . In addition , three public buildings were badly damaged during several hours of disorder , CNN affiliate BFM-TV reported . Amiens Mayor Gilles Demailly told BFM that the damage amounted to millions of euros . People were shocked and upset by the violence , he said . Images from the north Amiens neighborhood showed burned-out cars and the charred wreckage of a kindergarten and a sports center . Clashes were reported in the same area Sunday night , BFM reported . The latest violence , involving about 100 young people , broke out late Monday evening and carried into early Tuesday . The police officers were injured with buckshot , fireworks and projectiles , BFM reported . Police responded with tear gas but made no arrests . Speaking at a news conference in Amiens , Valls said that the violence shown toward police was `` unacceptable '' and that law and order must be restored . More security forces would be deployed Tuesday night to ensure there was no repeat of the trouble , he said . Valls said those suffering most from the disorder were the residents of the neighborhood affected . The area had already been designated a `` high security zone '' because of drug trafficking and other problems , he said , meaning extra resources were to be used there . A local resident told BFM the community was angered Sunday when police carried out an `` aggressive '' traffic stop as a funeral was being held for a young man killed in a road accident last week . Sabrina Hadji , a sister of the victim , said police fired shots as people -- including women , children and the elderly -- were gathered for the ceremony . The community is tired of being treated without respect and `` like animals , '' she told BFM , and a silent march was organized as an expression of `` anger because we are never listened to . '' Valls acknowledged there is tension between police and the community after the incident and said an inquiry has been ordered into the police operation . However , nothing excused violence directed at police and the torching of public buildings , he said . Valls said he had not come to Amiens to point the finger at anyone , but the rule of law must be followed . After the initial unrest Sunday , the mayor appealed for `` calm , respect and dialogue '' in a statement on the official website for Amiens , a city of about 130,000 people . Demailly urged communication between police and residents , saying it is important they have confidence in each other . Earlier Tuesday , Valls traveled with President Francois Hollande to the Var area , in southeastern France , to pay tribute to two women police officers who were killed in the line of duty in June , BFM reported . Hollande addressed the trouble in Amiens , saying that public security is `` not just a priority , but an obligation '' for authorities . More must be done to prevent and punish violence , delinquency and criminality , he told reporters . Hollande , who was sworn in as president three months ago , said the next budget would include additional resources for policing , after years of cutbacks . France has been shaken by unrest in poorer urban areas on several occasions in recent years , notably in 2005 , when the deaths of two young men of North African descent sparked weeks of rioting . CNN 's Alexander Felton and Laura Smith-Spark contributed to this report .
