All law enforcement agencies are maintained under Cuba's Ministry of the Interior, which is supervised by the Revolutionary Armed Forces. In Cuba, citizens can receive police assistance by dialing "106" on their telephones. The police force, which is referred to as "Policía Nacional Revolucionaria" or PNR is then expected to provide help. The Cuban government also has an agency called the Intelligence Directorate that conducts intelligence operations and maintains close ties with the Russian Federal Security Service.
