( CNN ) Three more cemeteries have been vandalized in France , at a time of heightened sensitivity over religion and terrorist threats . The Interior Ministry announced Wednesday that overnight , headstones were damaged in a small Christian cemetery in Saint-Beat in southern France and swastikas were scrawled in Jewish cemeteries in Challans , in the west , and Issoudun , in central France . Those three incidents are in addition to the defacing of tombstones in western France 's Tracy-sur-Mer and the desecration of about 250 graves late last week in a Jewish cemetery in Sarre-Union . Authorities took five teenagers -- one of whom turned himself in and none of whom have criminal records -- into custody in that incident and charged them with desecration of graves and with organized damage on property for the public benefit , Saverne prosecutor Philippe Vanier said Monday . One of the teens denied the attack was anti-Semitic , claiming they 'd thought the cemetery was abandoned and did n't notice the graves were Jewish until after the vandalism began , according to the prosecutor . Whatever the motive , the Sarre-Union vandalism spurred strong condemnations from French officials , with Prime Minister Manuel Valls calling it `` a vile , anti-Semitic act '' and Interior Minister Bernard Cazeneuve vowing , `` The French Republic wo n't allow another act against our values . '' The incidents come at a time when Jews in France have become targets , most glaringly with last month 's deadly hostage siege at a kosher supermarket in Paris . It 's not just France , though , as the recent shooting near a synagogue in Copenhagen , Denmark , illustrates . This all comes amid a push by groups like ISIS for its twisted version of Islam and against any nonbelievers , with Jews and Christians being singled out as targets . Muslims have also come under fire . After the Paris attack on the satirical magazine Charlie Hebdo and kosher market siege , numerous mosques in France were attacked -- with shots fired in some cases and other instances in which a pig 's head was stuck on a prayer room door and messages of hate were sprayed on walls , according to French media reports . CNN 's Laura Akhoun and Margot Haddad contributed to this report .
