Iranian Leader Threatens to Destroy Israeli Cities If Attacked

Tel Aviv and Haifa would be targeted, Khameni warns

Iranian Supreme Leader Ayatollah Ali Khamenei warned on Thursday that the Islamic Republic would destroy the Israeli cities of Tel Aviv and Haifa if its nuclear infrastructure came under attack from the Jewish state.

Israel puts little stock in big power negotiations aimed at curbing Iran's uranium enrichment - which Western nations suspect is a conduit to nuclear weapons capability - and has repeatedly hinted at pre-emptive war against its arch-enemy.

During a visit to Israel on Thursday, U.S. President Barack Obama acknowledged its security concerns, saying, "America will do what we must to prevent a nuclear Iran." But he also said big powers believed there was still time for a diplomatic solution.
