Eyal Zamir states that he cannot promise the Israeli population an "absolute success" and he warns that the "Iranian regime's response" can be harsh.
IDF (the army) will defend the Israeli home front and I ask you to take responsibility, for yourselves, for your families and your communities and follow instructions, he says.
Zamir calls Israel's attack on Iran a "historic campaign without equal".
He also comments on the "Iranian regime's" stated goal of "destroying the state of Israel" and that Israel assesses that the country is "closer than ever to develop nuclear weapons".
Weapons of mass destruction in the hands of the Iranian regime are an existential threat to the state of Israel and a significant threat to the wider world.
