Just after the celebration of Rosh Hashanah Wednesday night, a Jewish synagogue in Oakland was vandalized early Thursday morning with anti-Semitic graffiti. As KRON 4 reports, the rabbi at Temple Sinai found the graffiti when he arrived at 5 a.m. this morning, and the vandalism came just after reports of synagogues across the East Bay being on high alert watching for hate crimes.

As KRON 4 explains, "The graffiti was covered with paper, so people in the community could write love notes before the paint was cleaned off."

Temple Sinai is home to one of the oldest Jewish congregations in the Bay Area, having formed in 1875 and moved into its current home at 2808 Summit Street (near 28th and Webster) in 1914.

Rabbi Steven Chester of Temple Israel of Alameda earlier told KRON 4 that he had decided to install more security cameras ahead of this holiday week, saying, "There’s no choice — there’s really no choice." Last month, Temple Israel was the victim of an apparent hate attack when someone threw a rock through one of the building's windows.

Chester added that neither he nor his congregants were scared, however, "I find it very sad that we have to have security in this way because of what goes on in this society."

Meanwhile, we learn this week of an Alameda family who says that Alameda High School tried to sweep an incident under the rug involving a series of hateful, anti-Semitic texts that their freshman daughter received from other students, as ABC 7 reports.

Also last month in Alameda, some strange swastika flyers were found near the Islamic Center of Alameda, showing a woman wearing a hijab along with the words “Help me kill you stupid."
