U.S. says Iran fired on two oil tankers, but Iran says it didn't

President Trump says there’s absolutely no doubt that Iran was behind attacks this week on two oil tankers in the Gulf of Oman. This follows the U.S. military’s decision to release a video that it says shows Iranian forces removing an unexploded mine from one of the damaged ships. Iran has denied any involvement in the attacks, and essentially accused the U.S. of staging them. The Trump administration’s claims have been viewed with skepticism, including from some people on one of the tankers.
