Steve Witkoff, Donald Trump's special envoy for the Middle East, on Wednesday, January 21, on the sidelines of the Davos summit in Switzerland, described the killing of protesters in Iran as 'horrific' and called for a change in the behavior of the Islamic Republic. Witkoff emphasized that the United States is not in direct negotiations with Iran, but has been in contact with Iranian officials. He added that reaching a diplomatic agreement is conditional on a serious change in Tehran's behavior, and so far there has been no indication of the Islamic Republic's intention to change its course.
