1. More details are emerging about the synagogue shooting in California on Saturday — the latest in a disturbing series of attacks on houses of worship in the U.S. and beyond.

Minutes before the gunman opened fire with a military-style weapon, the authorities received warnings of an anonymous post on social media that contained threats, but no specifics of location. The 19-year-old taken into custody afterward had written a white supremacist manifesto.

Today, a funeral was held for Lori Gilbert Kaye, 60, who died in the shooting. A vigil was held last night, above. Rabbi Yisroel Goldstein, who was wounded, wrote of the attack for our Opinion section.
