Southern California law enforcement agencies planned to step up patrols at synagogues and other houses of worship with tensions escalating in the Middle East at the start of Rosh Hashanah.
The Los Angeles Police Department said the agency intends to have a "strategic presence" at locations across the area.
"We present this visual deterrent, and to have cops close by if, god forbid, something was to happen," said LAPD Commander Steve Lurie. "It's going to feel like there are a lot of police officers around because there are."

Israel has vowed retaliation.
