JERUSALEM -- Mordechai Vanunu, accused of exposing Israel's nuclear weapons secrets, rejected conditions for meeting his American girlfriend in jail Tuesday and kept up a three-week hunger strike, Israel radio said.
'Vanunu said he only wanted to meet face-to-face with her and he did not want their messages to each other to be censored,' the state-owned radio said.
Vanunu balked at meeting his girlfriend, Judy Zimet, after authorities at the undisclosed jail where he is held said the couple could meet only in the presence of prison officials and would be separated by a glass barrier.
The report said Vanunu, 32, decided to stay on a hunger strike begun Jan. 5. Earlier Tuesday, radio reports said the jailed former nuclear technician would end the strike after meeting with Zimet.
Vanunu is reported to be consuming only liquids.
Zimet, a resident of the Boston, Mass., area, arrived in Israel this month in hopes of meeting with Vanunu in the jail where he is awaiting trial on treason and espionage charges.
Zimet, in her late 20s, said in an interview Monday she will stay in Israel 'until I am allowed to meet Moti,' her nickname for Vanunu, whom she met on a visit to Israel a few years ago.
Zimet said she has not seen Vanunu since he vanished in London Sept. 30. His whereabouts was a mystery until Nov. 9, when the Israeli government announced he was in custody.
Vanunu, a former worker at the Dimona nuclear research plant in Israel's southern Negev Desert, disappeared five days before a British newspaper published an article saying Israel secretly built between 100 and 200 atomic warheads at Dimona.
The Sunday Times of London said its primary source for the article was Vanunu, a Moroccan-born Jew who was laid off his job at the plant in a reported cost-cutting move in November 1985.
Israel has a longstanding policy of refusing comment on its nuclear weapons capability, which the Sunday Times story said has given Israel the world's sixth-largest nuclear arsenal.
The Israeli government repeatedly has denied reports that agents of its Mossad foreign intelligence service kidnapped Vanunu in Europe and returned him to Israel to stand trial.
Vanunu, arriving for a court hearing Dec. 21 in Jerusalem, scribbled a message on his left palm and flashed it to reporters to indicate he was abducted just after landing at Rome's Fiumicino airport on a British Airways flight Sept. 30.
On Nov. 28, Vanunu was indicted on treason and espionage charges. Government prosecutors have decided against seeking the death penalty, so Vanunu faces up to 55 years in prison if convicted.
