DUBAI, United Arab Emirates (AP) — The United States expanded its airstrike campaign against Iran early Friday by hitting more bridges and apparently collapsing a tower at a key Iranian port, part of U.S. President Donald Trump’s threats to start striking infrastructure to pressure Tehran to ease its chokehold on the Strait of Hormuz. Iran launched new missile attacks against U.S.-allied nations in the Middle East, including Qatar, a key mediator in the war. The interim ceasefire agreed to last month has collapsed, and the region has endured days of back-and-forth attacks by the U.S. and Iran as they battle for control of the strait. Iranian officials say U.S. strikes have killed more than 35 people and wounded over 300 others, with new casualties reported in Friday’s strikes.When the U.S. and Israel launched the war on Iran on Feb. 28, Tehran effectively closed the strait to shipping traffic, a move that sent the price of oil soaring and gave Iran major leverage in negotiations.Speaking in a primetime address to the American public, Trump insisted the war was going well.“We are likewise winning big in Iran, and you will see the fruits of that labor very, very shortly,” Trump said.
