A "Chabad House" in the southern city of Sderot, on the Gaza border, has been vandalized with anti-Semitic graffiti, reports said.
The graffiti included swastikas, the report said.
Footage from security cameras shows a person arriving in the middle of the night and spray-painting malicious graffiti together with, in Russian, the statement that, "You are scum and thieves."
Since the start of Israel's war with Hamas, the Chabad house has served as a key operational center, providing support and food for both IDF soldiers and local residents.
On Monday morning, Israel Police opened an investigation into the matter.
"Israel Police takes this incident very seriously, and is investing all resources and means necessary in order to investigate the matter, collect evidence and proofs, and bring about the arrest of those involved," a police statement said
