The Justice Department on Friday announced major arrests of hundreds of members of international crime syndicates in South America, with the apprehensions being carried out by police from multiple countries.

An international team of law enforcement officials from the U.S., El Salvador, Guatemala and Honduras on Friday “announced criminal charges in Central America against more than 700 members of transnational criminal organizations, primarily MS-13 and 18th Street gangs,” the Justice Department said in a press release.

The arrests “resulted from a one-week coordinated law enforcement action under Operation Regional Shield,” the department said. ORS was launched in 2017 as an international collaboration between the U.S., Mexico and several other countries
