Netanyahu Says Iran Yet to Cross Nuclear 'Red Line'

Israeli Prime Minister Benjamin Netanyahu warned on Monday that Tehran's nuclear program was getting closer to crossing a crucial "red line" but had yet to reach it.

"It has not yet crossed the red line which I laid out in the United Nations but it is systematically approaching it and we cannot let it cross," he told senior members of his Likud-Beitenu political alliance in remarks broadcast on public radio.

In a September speech to the U.N. General Assembly Netanyahu described Iran's progress in uranium enrichment and drew a red line referring to the point at which Israel believes its arch foe would be able to build a nuclear bomb.

In a visit to Israel last week U.S. Defense Secretary Chuck Hagel vowed an "ironclad" commitment to the Jewish state's security, citing the planned multi-billion dollar sale of advanced U.S. aircraft and missiles.

He also insisted there was no serious rift between American and Israeli leaders over how to prevent Iran from attaining a nuclear weapons capability.

Israel, believed to be the Middle East's sole if undeclared nuclear power, has refused to rule out a pre-emptive military strike on Iran's nuclear facilities, which the Islamic republic says are for peaceful purposes.
