BUCHAREST, Romania (AP) — Romanian police have begun an investigation after anti-Semitic graffiti appeared on the house of late Nobel laureate Elie Wiesel in northwest Romania.

The probe was launched Saturday after comments were scrawled overnight on Wiesel's small house— a protected historical monument— in the town of Sighetu Marmatiei. One of the comments said Wiesel was "in hell with Hitler."

The Romanian group for Monitoring and Fighting Anti-Semitism called it an act of vandalism against the "memory of Elie Wiesel, the memory of the Holocaust victims and the souls of the Holocaust survivors."

Along with 14,000 Jews, Wiesel and his family were deported in May 1944 to Auschwitz from the town.

His mother and younger sister died there while he and his two older sisters survived. Wiesel died in 2016.
