Iran is preparing to "imminently" launch a ballistic missile attack on Israel, according to a senior U.S. administration official who warned of "severe consequences" should it take place. The official, who spoke on the condition of anonymity, said the United States is actively supporting Israeli defensive preparations. Iran’s state media has not suggested any attack is imminent. This comes after the Israeli military on October 1 warned people to evacuate nearly two dozen Lebanese border communities hours after announcing what it said were limited ground operations against Hezbollah. White House officials did not immediately offer any evidence backing its intelligence finding.
