The Venezuelan-born prisoner, whose real name is Ilich Ramirez Sanchez, is not getting adequate health care in France, and authorities there are denying his right to communicate with lawyers, Mr. Eusse charged.
“They have violated his human rights, he’s been incommunicado,” he said at a news conference on Monday.
Mr. Eusse described Ramirez’s health as “delicate,” without giving any details.
Ramirez is serving a life sentence for the 1975 murders in Paris of two French investigators and Michel Moukharbal, a Lebanese man who was an informant for the French government.
He also has been blamed for a series of Cold War-era bombings, assassinations and hostage dramas, including the 1976 hijacking of an Air France jet en route to Uganda.
He has testified that he led a 1975 attack that killed three people at the headquarters of the Organization of the Petroleum Exporting Countries in Vienna, Austria. Venezuela’s then-Oil Minister Valentin Hernandez Acosta was one of the 70 hostages seized by the attackers and later freed in Algeria.
Ramirez was captured in Khartoum, Sudan, in 1994 and hauled in a sack to Paris by French secret service agents. Venezuela’s government has questioned whether Ramirez’s rights were violated when he was abducted and whisked away to France.
It wasn’t known how Mr. Chavez’s administration would react to the Communist Party’s petition. Telephone calls to Venezuela’s Foreign Ministry seeking comment from government officials went unanswered.
Mr. Chavez has praised Ramirez in the past as a “revolutionary fighter,” saying he selflessly joined the Palestinian struggle as a member of the Palestine Liberation Organization. The comment raised concerns among Jewish groups such as the Simon Wiesenthal Center, which said Mr. Chavez condoned terrorism by eulogizing Ramirez.
