(CNN)From the Palestinian Territories to Mexico, videographer Trip Jennings has covered protests around the world. But it was on his home ground of Portland, Oregon, where he received his first significant injury.
A photojournalist who was shot in the eye says it's not just violent rioters being targeted in Portland
"I got hit right in the eye," Jennings told CNN, saying he suspects it was a pepper ball. "I remember seeing the lens of my gas mask shatter and then closing my eye and just blood inside of my mask."
"I blinked and I blinked and got some of the blood out of my eye and there was pepper spray and I think pepper powder all over me," the 37-year-old added.
"That moment of impact is really just burned in my memory. That vision of shards in my gas mask exploding. And then my face and body on fire from the pepper balls. I mean you can't forget that," he said.
Jennings says he started covering the Portland protests as a freelance journalist when they began earlier this spring. After taking a break, he said he returned to the scene last week and saw that tensions had visibly escalated after President Trump deployed federal agents to the city in early July.
Even with the suffocating tear gas in the air, the veteran journalist, whose work has been featured on National Geographic, PBS and other outlets, continued his work at Sunday's protest.
With a gas mask on his face and camera in hand, Jennings said he shot video and pictures of protesters demanding racial justice and an end to an influx of federal agents in their city.
But just after midnight, unidentified law enforcement officers ordered the protesters to disperse from the federal courthouse, using more impact ammunition -- which Jennings said included rubber bullets, beanbags and pepper balls, and tear gas -- than he said he'd ever seen in the city before.
People started running in all directions, falling over each other, according to Jennings, who said he took cover behind a car.
Video obtained by CNN of Sunday's protest shows a woman screaming as she's hit by rubber rounds. Another video shows law enforcement officials grabbing protesters and throwing them to the ground.
Protesters launched mortar-style fireworks over the fence around the courthouse, according to a statement by the Portland Police Bureau. Around 1 a.m., someone started a fire inside the fenced area that was quickly put out.
It is unclear whether the law enforcement officials in the videos were federal or local, but the PPB told CNN that none of its officers were the ones seen in the videos. And Monday, the PPB said its agency was not involved in dispersing the crowds.
The Department of Homeland Security and the US Marshals Service did not respond Monday to requests from comment from CNN. After CNN forwarded the video to US Customs and Border Protection on Monday for comment, spokesperson Stephanie Malin responded, "We're not going to be able to analyze every video of the response in Portland that comes to us and positively or negatively identify if they include our personnel."
