Dubai, Sept. 6 -- US forces struck three Iranian oil tankers on Saturday, U.S. Central Command said, including one off the coast of Kharg Island, near Iran's key oil export hub. The strikes were carried out after Iran's Islamic Revolutionary Guard Corps launched ballistic missiles at two US Navy ships, Central Command said. "Let the message to the IRGC be clear: If you shoot at two of our ships, we will impose an even higher economic cost - taking out three of yours," said Admiral Brad Cooper, head of US Central Command. Tasnim, the semi-official Iranian news agency, reported earlier that four US missiles hit a tanker in the area of Kharg's anchorage. Tasnim quoted local sources as saying there were no casualties and the tanker's crew was being evacuated.P23...
