Marxist militant Carlos the Jackal was sentenced to life imprisonment on Thursday by a French court for bomb attacks that killed 11 people nearly three decades ago.
The Venezuelan defendant, 62, whose real name is Ilich Ramirez Sanchez, has been locked up in France for almost 20 years serving a life sentence in a separate case for killing two police officers and an informant in Paris in 1975.
Sentencing Ramirez to an additional life term, the special terrorism court in Paris made up of seven magistrates said he should serve a minimum of 18 years in jail.
The verdict could push back the date on which he can apply for conditional release, currently set for 2012.
Venezuelan-born Ramirez was accused of masterminding four separate attacks in France on two trains, a train station and a Paris street that killed 11 people and wounded nearly 200.
Prosecutors said the bombings were his answer to the police seizure of two of his gang, including his lover, and had argued that he remained a danger to the public.
