The clip starts with two young kids going back and forth and then gunshots ring out, sending the kids running for their lives. In the video, you can hear parents screaming and a little girl yelling for help as she fights back tears.

Cops say more than 33 shots were fired in the exchange between the two groups in a Palo Alto neighborhood on Tuesday. 3 people were injured and 1 killed. It does not appear any kids were hurt.

In a press conference Tuesday, Police Chief Jeff Liu, said, "Shooting and violence, especially at our parks with kids playing is completely unacceptable. We need to come together as a community and send a message that this type of activity will not be tolerated."
