[Oscar Guerrero](/people/oscar-guerrero/) was a freelance journalist from [Colombia](/places/colombia/). He met [Mordecai Vanunu](/people/mordecai-vanunu/) in Sydney, [Australia](/places/australia/), where [Vanunu](/people/mordecai-vanunu/) was sharing top-secret photographs of [Israel's](/places/israel/) nuclear facility.[^1]

[Guerrero](/people/oscar-guerrero/) saw the photographs and proposed publishing them for a fee. He first approached *The Sydney Morning Herald*, but the photographs were rejected. His approach was, however, passed on to the [Australian Security Intelligence Organization](/organizations/australian-security-intelligence-organization/) (ASIO) and then to the [Australian Security Intelligence Service](/organizations/australian-security-intelligence-service/) (ASIS), who informed [Israel](/places/israel/).[Guerrero](/people/oscar-guerrero/) then tried *The Age* newspaper in Melbourne, and later the [London](/places/london/) papers.[^1]

[Nicholas Davies](/people/nicholas-davies/), a London *Daily Mirror* foreign editor and [Israeli](/places/israel/) agent, stalled [Guerrero](/people/oscar-guerrero/) by telling him the newspaper needed an expert to check his claims. [Guerrero](/people/oscar-guerrero/) had already struck a deal with *The Sunday Times* to publish [Vanunu's](/people/mordecai-vanunu/) story and photographs, with [Vanunu](/people/mordecai-vanunu/) receiving a £250,000 advance on a book and [Guerrero](/people/oscar-guerrero/) receiving a 10% cut. [Guerrero](/people/oscar-guerrero/) approached the *Mirror* because he believed he was being cut out of *The Sunday Times* deal.[^1]
