Sami Abu Zuhri, a Hamas spokesman, said in a press statement that the allegations published in the daily Haaretz is a "Zionist plot aimed at covering the Israeli involvement in the assassination of Hamas leader Mahmoud Al-Mabhouh."
Haaretz said on Wednesday Mosab Hassan Yousef, son of jailed Hamas leader Sheikh Hassan Yousef passed intelligence on Hamas' leadership to the Shin Bet for over a decade.
The report said the intelligence he supplied Shin Bet led to the exposure of a number of military cells, and to the prevention of dozens of suicide bombings and assassination attempts on Israeli figures.
According to the report, the Shin Bet considered Yousef, who converted to Christianity and now lives in California, as its most reliable source in the Hamas leadership. He earned the nickname "the Green Prince" - using the color of the Hamas' flag, and "prince" because of his pedigree as the son of one of the movement's founders and leaders in the West Bank.
Abu Zuhri added "it is the first time that the Israeli (external intelligence agency) Mossad disclosed the names of its spies in this manner."
The spokesman said the publication of these allegations aim at covering Mossad's involvement in the assassination of aAl-Mabhouh in Dubai, and the defilement of Hamas and the personality of Sheikh Hassan Yousef."
