Italian police say several Mafia suspects have been arrested in raids in Sicily, New York and Miami.
Police in Palermo say the crackdown on the Cosa Nostra crime syndicate was still being carried out Wednesday.
National police in Rome say 20 warrants have been issued so far in Palermo and six arrests have been made in the United States. Police say the crackdown targeted a Palermo-based Mafia crime family, and those named in the warrants are suspected of being mobsters and running extortion, money laundering and drug trafficking operations.
Police also released video of the Palermo raids showing Italian police and FBI agents discovering weapons, including guns stashed away in the rear compressor space of a refrigerator.
