Israel’s military chief Eyal Zamir has said that his country should be “ready for a prolonged campaign” against Iran, as the longtime foes exchanged fire for the eighth day, AFP reports.

“We have embarked on the most complex campaign in our history to remove a threat of such magnitude, against such an enemy. We must be ready for a prolonged campaign,” Zamir said in a video statement to Israelis, adding that “the campaign is not over. Although we have made significant achievements, difficult days still lie ahead.”
