The war in the Middle East spiraled further Monday as Israel and the U.S. pounded Iran. U.S. President Donald Trump said the campaign would likely take several weeks. Tehran and its allies hit back against Israel, neighboring Gulf states and targets critical to the world’s energy production. The intensity of the attacks, the killing of Iran's supreme leader, and the lack of any apparent exit plan indicated the conflict would not end anytime soon. It was already having far-reaching consequences.
