Charges were filed in Ventura County, California, against a suspect in the death of a Jewish protester. With anti Semitic incidents spiking all across the country, many Jewish communities aren't feeling safe. One Jewish group in Southern California is taking safety into their own hands. ABC's Jacqueline Lee in Los Angeles with the story.

Nestled deep in a canyon just an hour outside Los Angeles. But it feels like a war away.

Learning training is a forever process.

Under the hot sun, among the wildlife and steep terrain, hundreds of Jewish Americans are learning how to shoot guns for the very first time. What are people most scared of?

We know there are plenty of people out there who would kill us if they had the chance to. Your job is line up the sights and move the trigger.

Rabbi Yossi Isle Fort is leading the courses here and is founder of Maganam. To.

Just check the top of your sights. Don't look for the dot, look for the top of your sights.

In the last few weeks, we've seen over a 300% increase in call volume. Over 1000 calls fielded since October 7.

October 7, the deadliest single day for the Jewish people since the Holocaust. Hamas militants storming into Israel in a surprise attack by air, sea and land, taking hundreds of Israeli hostages and murdering and injuring thousands of others. Since October 7, antisemitism here in the US. Surging numbers from the AntiDefamation League show a meteoric 388% rise in hostility or prejudice against Jews in America.

Yes, I am scared.

Back at the gun range, leaders tell ABC News their call volume this October was 300% higher than last October, receiving roughly 1000 calls.

It's hard to function, but every single day we get stories. Every single day they identify more bodies. And it's a small country, so we're all affected.

Los Angeles resident Shelley Gal got the call hours after the attack. With family members and friends located in southern Israel, she's now stepping up her own firearms training.

When I visited a year ago, I was telling them, I don't think you guys are safe. You should all own guns. And they were kind of laughing at me. And unfortunately, it turns out to be true. And we are being targeted just by being Jewish. And I am originally from Israel, which I'm like, targeted wife, my appearance, I mean, anybody in the Middle East would right away spot me as an Israeli. So that's really uncomfortable.

The same day as the firearms training, a pro Israeli, pro Palestinian demonstration took place 40 minutes away in Thousand Oaks, California. Eyewitnesses say some sort of altercation occurred and 69 year old Jewish protester Paul Kessler fell backwards and hit his head. He died from his injuries the next day. The medical examiner ruled his death a homicide. In DC. This week, thousands marching to the Capitol.

Fear of loss is a good motivator so a lot of people start from there, and our goal is to take that and turn it into a healthy approach to how we can do this responsibly. How many of you felt you were missing all over the place?

A growing number of Jews here at this gun range now willing to put their safety literally in their own hands. Are you prepared to kill someone?

I'm not ready to kill. I'm not planning on killing. But if a situation arise and you have to, and that's for survival, you have to do what you have to do.

Thanks to Jacqueline from California.
