Iran “won’t be alone” if the United States decides to launch a military strike on the Islamic republic, a senior Russian diplomat said on Wednesday.

U.S. President Donald Trump targeted Iranian Supreme Leader Ayatollah Ali Khamenei and other top Iranian officials with sanctions on Monday. The dramatic step to increase pressure on Iran follows Tehran’s downing of an unmanned American drone last week, which Russia said had violated Iranian airspace. On Tuesday, Trump threatened to obliterate parts of Iran if it attacked “anything American,” but later left the door open for talks.
