Iran's Foreign Minister Mohammad Javad Zarif says the Trump administration is showing “disrespect” towards Tehran, AFP reported Saturday. He added that his country is open to prisoner swap negotiations with the U.S., but only if the Trump administration shows a "change of attitude." His comments were made in an interview with CBS, set to air in full on Sunday. Negotiations are a "possibility certainly from a humanitarian perspective, but it requires a change of attitude," Zarif said. Five Americans are held in Tehran, including 81-year-old Baquer Namazi, who is in failing health. Zarif blasted the U.S. administration for showing "disrespect"...
