The U.S. government has designated six Mexican cartels as foreign terrorist organizations, according to a public notice from the Department of State.

The United States on Wednesday designated Tren de Aragua, the Sinaloa Cartel and other drug cartels as global terrorist organizations, according to a Federal Register notice, a move that comes as President Donald Trump steps up immigration enforcement against alleged gang members in the U.

The designation opens the door for possible financial sanctions against the groups and those who are linked to them.
