Speaking to his Cabinet, Netanyahu said the world had become a “more dangerous place” as a result of the deal.
He reiterated a long-standing threat to use military action against Iran if needed, declaring that Israel “has the right and the duty to defend itself by itself.”
Sunday's agreement is just the first stage of what is hoped to bring about a final deal ensuring that Iran does not develop a nuclear weapon.
Under the deal, Iran will curb many of its nuclear activities for six months in exchange for limited and gradual relief from painful economic sanctions.
