Two Jewish cemeteries in eastern Germany have been desecrated in an anti-Semitic attack, police said Monday. Police said a pig's head and an anti-Semitic banner were left at the gate of a cemetery in the city of Gotha. They said that several glasses containing a red blood-like liquid were thrown over the cemetery's gate. In Erfurt, a memorial plaque at the entrance gate to a Jewish cemetery was also covered in a red liquid. Police were analyzing the liquid to determine what it is. The damage to both cemeteries was discovered Monday morning. Both cities are in the state of Thuringia, whose top security official, Interior Minister Manfred Scherer, said police and prosecutors were working to find the perpetrators.
