A crowd of more than 100 people pelted Border Patrol agents with rocks and bottles as they tried to cross into the U.S. illegally, according to U.S. Customs and Border Protection.

The incident happened Sunday in the Tijuana River channel, near the San Ysidro Port of Entry.

According to CBP, a Border Patrol agent ordered the Mexican nationals to stop, but they continued walking into the U.S.

Officials said the agent fired a PepperBall Launcher, but it did not deter the crowd.

“They had their phones out so this group was out to spark an incident. That's what they wanted to do, “ Border Patrol Union representative Gabriel Pacheco said.

Had cooler heads not prevailed it could have ended much worse, he said.

Even with reinforcements, agents were outnumbered, dodging threats, rocks and bottles.

More agents responded as the crowd became “unruly,” even hitting one agent in the head with a full water bottle, officials said.

According to CBP, the agents used “intermediate use-of-force” devices, and the group retreated back to the Mexican side of the border.

No one was arrested.
