Mexico says it is continuing to make arrests as part of its Operation Northern Border effort to crack down on drug smuggling networks.

Mexico’s security secretary, Omar García Harfuch, said Tuesday more than 1,000 people have been arrested as part of the operation since June 10. More than 4,000 suspects have been detained under the program since its start in February.

In the past two weeks, Harfuch said Mexico has also confiscated nearly 700 firearms as part of Operation Northern Border, which includes Mexico’s National Guard, Marines and attorney general.

Mexican President Claudia Sheinbaum’s administration started the program shortly after the Trump administration threatened tariffs on Mexico if it doesn’t do more to stop the flow of fentanyl across the U.S.-Mexico border.
