WASHINGTON (AP) — Tensions between Washington and Tehran flared anew Wednesday as Iran's Revolutionary Guard conducted a space launch that could advance the country's long-range missile program and President Donald Trump threatened to "shoot down and destroy" any Iranian gunboats that harass Navy ships.
The launch was a first for the Guard, revealing what experts described as a secret military space program that could accelerate Iran's ballistic missile development, which is a major source of U.S. and international criticism. American officials said it was too early to know whether an operational Iranian satellite was successfully placed into orbit. Trump's top diplomat accused Iran of violating U.N. resolutions.
