Jewish High Holidays begin at sundown

The Jewish High Holidays begin at sundown with Rosh Hashanah, the Jewish New Year. They'll culminate with Yom Kippur, the Day of Atonement, starting Sept. 20. A company that provides safety advice to Jewish groups has been offering in-person and online training on how to respond to active threats. Secure Community Network says its work has become more complicated as antisemitic threats come from a wider variety of domestic and foreign sources — ranging from proxies of Iran to white supremacists in this country. Violent attacks targeting American Jews this year include the assault at a Manhattan synagogue last month, a truck-ramming at a temple in Michigan in March, and an arson attack on a synagogue in Jackson, Mississippi, in January.
