The United States government is formally designating eight Latin American organized crime groups that also operate in the U.S. to be “foreign terrorist organizations.”

From Mexico's most ruthless drug cartels to Central America's most notorious street gang, these are the eight drug trafficking groups being designated terrorist organizations by US President Donald Trump's administration.

Trump signed an executive order on his first day in office directing Secretary of State Marco Rubio to explore designating major cartels as “foreign terrorist organizations.” Early this month, Rubio moved to designate six Mexican cartels and two other groups as FTOs.
