Iran threatened Saturday to strike Israel's nuclear installations if it is attacked by the Jewish state, Reuters reported. "If the Zionist Regime attacks Iran, we will surely strike its nuclear facilities with our missile capabilities," Revolutionary Guards commander-in-chief Mohammad Ali Jafari told Iran's Arabic language al-Alam TV station. On Wednesday US Secretary of State Hillary Clinton said that despite that fact that if Iran attained a nuclear weapon her country would safeguard the region with a "defensive umbrella," a diplomatic solution was still possible. "We will still hold the door open [for talks with Iran], but we also have made it clear that we'll take actions, as I've said time and time again, crippling action, working to upgrade the defense of our partners in the region," Reuters quoted Clinton as saying. She was in Thailand to take part in the ASEAN Regional Forum, an annual gathering of 27 Asian, US and European ministers, to discuss North Korea, Myanmar and a range of other regional security issues.
