According to the statement, two Palestinian women were arrested last month at the Erez crossing following Shin Bet intelligence reports. The two planned to carry out suicide bombings in Tel Aviv and Netanya.
Admitting affiliation with Islamic Jihad, the two confessed to taking advantage of the Israeli humanitarian-aid policy, which allows Palestinians access to Israeli medical care and facilities.
The bombings were to take place in crowded locations, such as bus-stops, restaurants or public halls.
Fatma Younis Hasan-Zack, a 39 year-old Gazan, had been running the Islamic Jihad employment center for women for the past four years.
Familiar with many of the organization's activists, Zack was the liaison between them and many women interested in carrying out suicide bombings.
About three months ago, Zack was approach by her niece, a mother of four from Gaza, who wanted to commit a suicide attack. Zack decided to carry out a bombing as well, and contacted the Islamic Jihad.
The two went on to secure false papers stating a medical condition allowing them to get to Ramallah for a medical examination which would secure a referral to an Israeli hospital.
Both underwent the Jihad's weapons training and were given explosive devices, and instructions as to what they should wear in order not to arouse suspicion.
The two were arrested at the Erez crossing, on May 20, following a specific intelligence report the Shin Bet received.
Over the last few years, more and more Palestinian women have been willing to carry out suicide bombings.
The Shin Bet statement said the two took a cold, deliberate advantage of Israel's humanitarian-aid policy.
