This news from Jerusalem: Former Israeli Prime Minister Shimon Peres revealed rare details about the Iran-Contra affair yesterday, saying that he and two other former Israeli premiers unanimously agreed on participating in the deal. Appearing on a talk show on Israel TV, Peres also expressed shock that then-President Reagan withheld information from top U.S. officials about the controversial deal to sell arms to Iran in the mid-'80s. The weapons, including anti-tank missiles, were sent to Iran in exchange for Iran's agreement to work for the release of U.S. hostages held in Lebanon by pro-Iranian Shiite Muslims. At the time, both Israel and the U.S. publicly condemned arms sales to Iran.
