Israeli air defence are intercepting Iranian missiles after Tehran warned it would attack Israel as a response to Israeli strikes on Beirut.

"A short while ago, sirens were sounded in several areas across the country, following the identification of missiles launched from Iran toward the State of Israel," the military said, in a statement.

The army added that sirens were activated in northern Israel.

Iran’s Revolutionary Guard announced earlier on Sunday that it was ready to launch an attack on Israel, after Iranian Supreme Leader Mojtaba Khamenei reportedly authorised the attack in response to Israeli strikes on Beiru, in a statement reported by Iranian state TV.
