President Donald Trump's Pentagon chief triggered a deluge of backlash Thursday night after a report that American forces struck a civilian highway bridge near Tehran twice on Thursday as Iranian villagers gathered nearby to celebrate the final day of the Persian new year. A U.S. military official, speaking anonymously to The New York Times, confirmed American forces struck the B1 bridge twice, in what's colloquially called a "double tap," claiming it was a planned military supply route for Iran's missile and drone forces. Iran's deputy governor of Alborz province flatly rejected the U.S. characterization, telling state media the bridge was not yet operational and that "there was absolutely no military activity on bridge B1."
