Paris  - French President Nicolas Sarkozy and several other conservative politicians have in recent days been the targets of letters threatening their lives, French media reported on Tuesday.

Sarkozy, Interior Minister Michele Alliot-Marie, Justice Minister Rachida Dati, Culture Minister Christine Albanel and the mayor of Bordeaux, Alain Juppe, have all received letters containing implicit threats to their lives and 9mm bullets.

The letter to Juppe, a former prime minister, contained the message: "You believe that you control our lives, but no, it is we who control yours and those of your families."

The letter also made reference to a group calling itself Earth-Solidarity and threatened Sarkozy, Alliot-Marie and Dati.

Last month, two right-wing parliamentarians in southern France had received similar threats accompanied by bullets.

France Info radio reported Tuesday that investigators believe that the letters are likely the work of a mentally disturbed individual. (dpa)
