PARIS — The international terrorist and self-professed Marxist revolutionary known as Carlos the Jackal received a life sentence — his third — on Tuesday, this time for a 1974 attack on a Paris drugstore that killed two people and wounded 34.

Carlos, whose real name is Ilich Ramírez Sánchez, was found guilty by a panel of five judges in a special terrorism court of tossing a hand grenade onto the crowded floor of the store in September 1974.

The guilty verdict was welcomed by the survivors and the victims’ families, Georges Holleaux, a lawyer representing the widows of the two men who died in the attack, said in a telephone interview. “The lesson is that when it comes to terrorism, one should never, never, never give up,’’ Holleaux said.

But Francis Vuillemin, one of Ramírez’s lawyers, vowed to appeal the decision.

The trial was the climax of a legal saga that began in 1983, when a judge dropped the charges for lack of evidence. The case was reopened in 2010, based on new evidence.

Ramírez, 67, who was born in Venezuela, has been incarcerated in France since shortly after his capture in Sudan by French agents in 1994, and is already serving two life sentences. The first was handed down in 1997 in the killing of two French police agents and a Lebanese informer in 1975, and the second in 2011 for a string of attacks in France in 1982 and 1983.

The third sentence almost guarantees that Ramírez will spend the rest of his life in prison.
