The Trump administration is barring Iran’s top diplomat from entering the United States this week to address the United Nations Security Council about the U.S. assassination of Iran’s top military official in Baghdad. Iranian Foreign Minister Mohammad Javad Zarif requested a visa a “few weeks ago” to enter the United States to attend a Jan. 9 Security Council meeting on the importance of upholding the U.N. Charter, according to a diplomatic source familiar with the matter. The Thursday meeting was to provide Tehran’s top diplomat with his first opportunity to directly address the world community since U.S. President Donald Trump ordered the Jan. 3 drone strike that killed Maj. Gen. Qassem Suleimani, a top Iraqi militia leader, among others. The Iranian government was awaiting word on the visa when on Monday a Trump administration official phoned U.N. Secretary-General António Guterres to inform him that the United States would not allow Zarif into the country, according to the Washington-based diplomatic source.
