U.S. Border Patrol agents exchanged gunfire with suspected cartel members near the U.S.-Mexican border on Monday, as the U.S. government’s response against criminal migrants continues to intensify.

The gunfire exchange – which happened exactly one week after President Donald Trump began ramping up border security on his first day in office – occurred at around 2 p.m. local time near Fronton, Texas.

A group of illegal aliens was attempting to cross the Rio Grande while bullets were fired, but did not make it across. Neither the Border Patrol agents nor the suspected cartel members were hit. 

President Trump recently designated Mexican drug cartels as foreign terrorist organizations. 

The area where the gunfire exchange took place is near Fronton Island, also unofficially known as “Cartel Island” due to the criminal activity there. In an interview with Fox News Digital in 2023, Commissioner Dawn Buckingham said that she declared the land as Texas territory – even though it had not officially been before – to grant law enforcement the right to patrol there.

Last week, a Fox News Digital exclusive found that a sharp drop in illegal immigrant encounters occurred in the first days of the Trump administration – 35% lower than the final three days of the Biden administration.

Department of Homeland Security (DHS) sources said that there were 1,288 encounters nationwide on Jan. 17, then 1,266 on Jan. 18 and 1,354 on Jan. 19. The 3,908 encounters in the last few days of the Biden administration countered the 2,523 encounters in the first three days of the Trump administration: 1,073; 736; and 714 from Jan. 20 to Jan. 22, respectively.

“Enforcing our Nation’s immigration laws is critically important to the national security and public safety of the United States,” Trump said in an executive order last week. “The American people deserve a Federal Government that puts their interests first and a Government that understands its sacred obligation to prioritize the safety, security, and financial and economic well-being of Americans.”
