The United States-Mexico border has become the scene of violence normally associated with countries such as Iraq and Syria.

The Mexican military has recovered no fewer than 10 improvised explosive devices at the international frontier this week, according to Fox Business.

The devices in question were recovered south of the border in the area of Pima County, Arizona.

U.S. Customs and Border Protection is urging Border Patrol agents to be wary in the area in light of the use of IEDs.

The devices were found after gunshots were observed at the border by a Border Patrol agent on Wednesday.

No one appears to have been injured in the use of the devices, long associated with terrorist groups.

A man armed with an AK-style rifle and two loaded magazines was subsequently arrested on the U.S. side of the border.

A federal law enforcement source informed Fox Business that the gunshots in question were presumably linked to a drug cartel dispute over border territory for drug and human smuggling operations.

“Exercise extreme caution and … report any possible armed subjects approaching the border with possible explosive devices,” the federal agency ordered agents in a memo obtained by Fox Business.

Illegal infiltration of the border continues on an unprecedented scale.

More than 10,000 illegal migrants have been apprehended at the southern border every day this week.

The federal government closed one border crossing in southern Arizona in response to the tidal wave of migrants flowing through earlier this week, according to the Associated Press.

Republican legislators are urging the Biden administration to make changes to the United States’ notoriously lenient asylum laws as a solution to the brewing crisis, according to The New York Times.

Record-setting levels of illegal aliens have breached the border under Biden’s tenure.
