The Latest: Trump says Iran war could last weeks as Netanyahu defends decision to attack

President Donald Trump says the United States can keep its military campaign against Iran going longer than the planned four-to-five-week time frame he gave earlier. Across Tehran, the sound of explosions rang out through the night and into the early morning hours Tuesday. The U.S. and Israel continue to pound Iran after killing Supreme Leader Ayatollah Ali Khamenei on Saturday. Iran and its allies are striking back at Israel, Gulf states in the region and targets tied to oil and gas production.
