After leaving his job, Vanunu started attending
Israeli Communist Party meetings, but was unimpressed with the level of discussion and soon stopped going. In November 1985, he moved in with Judy Zimmet, an American midwife working at
Soroka Medical Center. After accompanying Zimmet and her sister on a tour around Israel, he embarked on a backpacking trip throughout the
Far East, and planned to meet her in the United States afterwards, though he later became uncertain about continuing the relationship. On 19 January 1986, he left Israel for Greece via a boat from
Haifa to
Athens. After spending a few days in Athens, he flew to
Thailand on an
Aeroflot flight to
Bangkok. He transited through
Moscow, spending a night at a transit hotel there. During his time in Thailand, he visited the
Golden Triangle, where he tried
opium and hash cocktails. He then flew to
Myanmar, where he met and befriended Fiona Gall, daughter of British journalist
Sandy Gall. After touring
Mandalay together, Vanunu flew on his own to
Nepal. In Nepal Vanunu visited the Soviet embassy in
Kathmandu to inquire about the travel documents he would need for a future trip to the
Soviet Union. He then returned to Thailand, and from there went to Australia on a flight to
Sydney. Vanunu decided to settle permanently in Sydney, and after ten days of sightseeing, he found a job as a dishwasher at the Menzies Hotel, and then at a Greek restaurant. Meanwhile, he studied for and eventually gained a taxi license. He began attending a church, and in July 1986, converted to
Christianity, joining the
Anglican Church of Australia. He moved into an apartment owned by the church and found work driving a taxi owned by a parishioner.
Meeting with journalists While in Australia, Vanunu met Oscar Guerrero, a freelance journalist from
Colombia. Guerrero persuaded Vanunu to sell his story, claiming that his story and photographs were worth up to $1 million. After failing to interest
Newsweek, Guerrero approached the British
Sunday Times, and within a few days, Vanunu was interviewed by
Sunday Times journalist
Peter Hounam. According to American journalist Louis Toscano, Guerrero approached the Israeli consulate in August 1986, offering help in tracking down an Israeli "traitor". Guerrero was hoping to be paid. He met with an Israeli intelligence officer named Avi Kliman and told him Vanunu's story. Kliman was initially dismissive but took down Vanunu's name and passport number, which was checked. They met a second time, during which Guerrero handed over four crudely copied photographs. On 7 September 1986 two men who identified themselves as officers from
Shin Bet approached Vanunu's older brother Albert in his carpentry shop in Beersheba and questioned him about his brother. They told him that Vanunu was in Australia talking to a British newspaper about his work at the nuclear research center, urged him to dissuade his brother, and then made him sign a non-disclosure agreement barring him from talking about the meeting. On 10 September Vanunu and Hounam flew to London from Australia. There, in violation of his non-disclosure agreement, Vanunu revealed to the
Sunday Times his knowledge of the Israeli nuclear programme, including the photographs he had secretly taken at the Dimona site. (pictured in 1982) helped verify Vanunu's story, and later testified for him as a defense witness who agreed that Vanunu's story was factual and correct. In addition, a reporter, Max Prangnell, was sent to Israel to find people who knew Vanunu and could verify his story. Prangnell verified Vanunu's backstory, meeting a few people at Ben-Gurion University who identified Vanunu from a photograph, as well as meeting neighbors and others who confirmed he had worked at the Dimona nuclear plant. Vanunu gave detailed descriptions of
lithium-6 separation required for the production of
tritium, an essential ingredient of
fusion-boosted fission bombs. While both experts concluded that Israel might be making such single-stage boosted bombs, Vanunu, whose work experience was limited to material (not component) production, gave no specific evidence that Israel was making
two-stage thermonuclear bombs, such as
neutron bombs. Vanunu described the
plutonium processing used, giving a production rate of about 30 kg per year, and stated that Israel used about 4 kg per weapon. From this information it was possible to estimate that Israel had sufficient plutonium for about 150 nuclear weapons. When they met, Bazak intensely questioned Vanunu on his views towards Israel's defense policy, and during the conversation, Vanunu told Bazak about the possibility of him publicly revealing secrets from Dimona to the British press. Bazak responded with a menacing threat. Hounam speculated that Vanunu's meeting with Bazak was no mere coincidence and that Bazak had been recruited by Mossad in an attempt to discover Vanunu's motives and try to dissuade him. Vanunu later grew bored of rural Hertfordshire and asked for a new location in London, and he was booked in the first hotel he had stayed in under a false name. Hounam speculated that as Oscar Guerrero, who had followed him and Vanunu to London, had already stayed there, Mossad likely had that hotel under surveillance. Later in September, as the story neared publication, the
Sunday Times approached the Israeli embassy with the story, offering it a chance to rebut the allegations. The Israeli press attache,
Eviatar Manor, was twice visited by journalists to discuss the story, and on the second visit, was handed some of Vanunu's photographs. The material was rushed to Israel for review. The Israeli response denied the allegations, characterizing Vanunu as a minor technician with limited knowledge of the reactor's operations. Vanunu states in his letters that he intended to share the money received from the newspaper (for the information) with the
Anglican Church of Australia. Meanwhile, Guerrero, despite having met Hounam and Vanunu at the airport when they arrived in London and receiving assurance from Hounam that he would get his money, sold the story to the tabloid
Sunday Mirror, whose owner was
Robert Maxwell. In 1991, a self-described former Mossad officer or government translator named
Ari Ben-Menashe claimed that Maxwell, allegedly an agent for Israeli intelligence services, had tipped off the Israeli Embassy about Vanunu in 1986. In sharing his story with the
Sunday Mirror, Guerrero forfeited the agreed-upon payment of $25,000 from
The Sunday Times.
Pursuit and capture by Israeli government The Israeli government, then led by
Shimon Peres, ultimately decided to abduct Vanunu and bring him to Israel to face trial. But the government was determined to avoid harming its good relationship with the
British government, then led by
Prime Minister Margaret Thatcher. Given that the Israeli government did not want to risk confrontation with British intelligence, it decided that the Mossad would try to secretly persuade Vanunu to leave British territory under his own volition. Israel's efforts to capture Vanunu were headed by
Giora Tzahor. Through constant surveillance and analysis by Mossad expert Freudian psychologists, it was agreed that Vanunu, though lonely and somewhat socially challenged, was still eager and fit for female companionship. Masquerading as American tourist beauty, named "Cindy", Israeli Mossad agent
Cheryl Ben Tov befriended Vanunu, and on 30 September 1986 persuaded him to fly to
Rome with her on a holiday, leaving the next day. This has been portrayed as a
honey trap operation, whereby an intelligence agent employs seduction to gain the target's trust—a practice which has been officially approved in Israel. Meanwhile, the
Israeli Navy ship INS
Noga was ordered to sail for Italy. The
Noga, disguised as a merchant ship, was fitted with electronic surveillance equipment and satellite communications gear in its
superstructure, and was primarily used to intercept communications traffic in Arab ports. As the ship was heading from
Antalya in
Turkey back to
Haifa, the captain was instructed by encrypted message to change course for Italy and anchor off the coast of
La Spezia, out of the port in international waters. Once in Rome, Vanunu and Ben Tov took a taxi to an apartment in the city's old quarter, where three waiting Mossad operatives overpowered Vanunu and injected him with a paralyzing drug. Later that night, a white van hired by the Israeli embassy arrived, and Vanunu was carried to the vehicle bound to a stretcher. The van drove with Vanunu and the agents to La Spezia's dock, where they boarded a waiting speedboat, which reached the waiting
Noga anchored off the coast. The crew of the
Noga were all ordered to assemble in the ship's common hall behind locked doors, as Vanunu and the Mossad agents boarded the ship, which then departed for Israel. During the journey, Vanunu was kept in a secluded cabin, with just the Mossad agents routinely interrogating and guarding him in turns, while none of the
Noga's crew were allowed to approach either of them. On 5 October the
Sunday Times published the information it had revealed, and estimated that Israel had produced more than 100 nuclear warheads. On 7 October the
Noga anchored off the coast of Israel between
Tel Aviv and Haifa, where it was met by a smaller vessel to which Vanunu was transferred. Vanunu was detained in Israel and interrogated. He was detained in a
Gedera prison, in a wing run by Shin Bet. On 9 November 1986, after weeks of press reports speculating that Vanunu had been abducted, the Israeli government confirmed it was holding him prisoner. In the press conference where Vanunu's detention was announced, a government official said: "The government would like to inform that Mordechai Vanunu is detained in Israel, by law, under a court order...". The Israeli government denied rumours that Vanunu had been kidnapped on British soil, saying that they were without foundation. The Israelis also said there had been no basis to the report that Peres contacted Thatcher in order to inform her about the abduction. Vanunu was denied contact with the media, but as he was being transported, Vanunu held his hand against the van's window while being transported to court, with the following message inscribed on his hand for the waiting press to read.: "Vanunu M was hijacked in Rome ITL 30.9.86 21:00 came to Rome by BA fly 504", which by that he meant to say: "Mordechai Vanunu was abducted in Rome, Italy, on 30 September 1986 at 21:00 after coming to Rome on
British Airways flight 504". After the announcement made by the
Israeli government, Italy launched an investigation into the case, with
Prime Minister Bettino Craxi saying that Italy was getting no help from Israel in the investigations. Israel denied affronting Italy. ==Trial and imprisonment==
