Customs and Border Protection is telling its Border Patrol agents to use “extreme caution” after the Mexican military found ten IEDs at the border after a cartel gang fight.

The IEDs were found at the southern border near the Tucson area in Pima County, Arizona.

U.S. Customs and Border Protection is warning agents to be on the lookout for explosive devices.

A federal law-enforcement source shared with FOX Business Network an internal officer safety alert dated December 13th that warns CBP agents to be vigilant after the Mexican military seized 10 improvised explosive devices (IEDs) at the border.

The IEDs were found by Mexican authorities after Tucson border patrol observed gunshots at the U.S.-Mexico border and a Tucson supervisory border patrol agent arrested an armed person on the U.S. side who had a loaded AK-47 rifle, two loaded AK magazines, loose rounds and a handgun.

CBP is warning its agents to “exercise extreme caution and should report any possible armed subjects approaching the border with possible explosive devices,” according to the memo.

A source tells FOX Business this cartel gun fight erupted over a gap in the border fence at the ranch that is typically used to smuggle drugs through. Now it’s a magnet for the cartel for human smuggling — and the gangs were fighting for control.

It’s insane that we now have cartel gangs fighting over the use of certain corridors for drugs or human smuggling. This is how bad the border has gotten under Joe Biden, yet nearly every Democrat still defends Biden over this catastrophe and won’t do a damn thing about it.
