Iran fired off its latest rhetorical shot at the US -- unveiling a huge billboard in Tehran of President Trump’s face with an image of a choked Strait of Hormuz draped across it.

Iran wants the US to test its strength, said Ali Rafiei Atani, an IRGC commander in Qazvin province

“OFAC is issuing this alert to warn US and non-US persons about the sanctions risks of making these payments to, or soliciting guarantees from, the Iranian regime for safe passage."

President Trump has called off sending a US delegation to Pakistan Saturday for peace talks with Iran – canceling a trip he said would be a waste of time.
