(CNN) A cross-border raid by U.S. and Mexican law enforcement officials resulted in the arrest of 24 Sinaloa cartel members, authorities said.

The sting occurred Friday around the Arizona border with Mexico, local media reported.

It also netted “assault-type weapons” and hundreds of pounds of narcotics, said spokeswoman Gillian M. Christensen of the U.S. Immigration and Customs Enforcement.

The raid, dubbed Mexican Operation Diablo Express, targeted “high-level” Sinaloa cartel members who operate in the United States and the Mexican state of Sonora.

“The operation targets criminal elements and organizations operating in and around Sonoyta, Mexico,” a statement from Christensen said.

Mexican federal officers were brought in to the United States to ensure safety during the operation.

“Due to the sensitive nature, this operation was conducted with utmost secrecy to maintain the element of surprise and to ensure the safety of the Mexican law enforcement officers executing it,” Christensen said.

Those arrested are in the custody of the Mexican government, but Christensen said the United States will seek their extradition.
