DOCUMENTS INDICATE IRAN HAS NUCLEAR WEAPONS ISRAEL LINE THURSDAY, APRIL 9, 1998 According to Iranian government documents in Israel's possession, Iran received several nuclear warheads from a former Soviet republic during the early 1990s, THE JERUSALEM POST reported. The documents have been deemed authentic by United States congressional experts and are still being studied in Israel. They contain correspondence between Iranian government officials and leaders of Iran's Revolutionary Guards that discusses Iran's successful efforts to obtain nuclear warheads from former Soviet republics. The documents appear to bolster reports from 1992 that Iran received enriched uranium and up to four nuclear warheads from Kazakhstan, with help from the Russian underworld. Meanwhile, U.S. envoy Robert Gallucci held talks in Israel with Government and intelligence agency leaders concerning Russian aid to Iran's ballistic missile program. "The Government acts on priorities, and at the top is the Iranian missile program," an Israeli official said. Israeli officials said that Jerusalem and Washington agree on the extent of Iran's progress in developing the new missile, which would be capable of reaching Israel. However, they disagree on whether the Russian government acquiesces in the transfer of Russian missile technology to Iran and whether Moscow is capable of stopping the flow.
