The Iranian Supreme Leader’s warning for a full-blown battle with Israel comes as the country’s armed forces said that they used hypersonic missiles to attack Israel in overnight strikes as the conflict enters its sixth day. Iran intensified its offensive against Iran even as United States President Donald Trump called for the country’s “unconditional surrender”.
