Pedro Inzunza Noriega and his son, Pedro Inzunza Coronel allegedly ran one of the world's largest and most sophisticated fentanyl production networks, federal prosecutors said.

The indictment targets the leaders of the Beltran Leyva Organization, a faction of the Sinaloa Cartel that is running the purportedly largest fentanyl production network in the world.

Two leaders of the Sinaloa Cartel on Tuesday were hit with narco-terrorism charges for their alleged involvement in trafficking "massive" amounts of drugs into the U.S.
