Content: A patrol vehicle was struck by shrapnel from artillery rounds fired by the U.S. Marine Corps during a live-fire demonstration on Saturday at Camp Pendleton, California. The incident occurred around 1:45 p.m. as part of the Marine Corps' 250th anniversary celebration, which included a demonstration attended by Vice President JD Vance and Secretary of War Pete Hegseth.

The California Highway Patrol (CHP) reported that the shrapnel fell from an explosive ordnance that detonated prematurely while being fired over Interstate 5. This stretch of freeway, which connects Los Angeles to San Diego, was closed for several hours during the event, affecting approximately 80,000 daily commuters.

CHP officials stated that the shrapnel caused a dent and scratch on the patrol vehicle's hood. Officers at the scene described the sound of the falling debris as resembling "pebbles" hitting their motorcycles. Fortunately, no injuries were reported.

The freeway closure was implemented after the federal government notified the state about the live artillery fire. Initially, military officials had assured that no live rounds would be fired over public areas. However, on Saturday morning, electronic highway signs were updated to warn drivers of "LIVE WEAPONS OVER FREEWAY."

In response to the incident, the Marine Corps immediately canceled further live ordnance firing over the freeway. A safety sweep was conducted afterward, but no additional shrapnel was found. Camp Pendleton officials have launched an investigation to determine the cause of the premature detonation.

CHP Border Division Chief Tony Coronado expressed concern over the unusual situation, stating, "It is highly uncommon for any live-fire or explosive training activity to occur over an active freeway." He emphasized the importance of public safety and the need for improved communication between federal, state, and local agencies for future events.

California Governor Gavin Newsom addressed the incident on social media, stating, "We love our Marines and owe a debt of gratitude to Camp Pendleton, but next time, the Vice President and the White House shouldn’t be so reckless with people’s lives for their vanity projects."

The event, which drew around 15,000 military personnel and veterans, was part of a larger celebration that coincided with protests against the Trump administration occurring across Southern California. The freeway was closed between Harbor Drive and Basilone Road from 11 a.m. to 3 p.m., with the decision to close it announced only on the day of the event, leading to criticism from state officials.
