Hours after the White House imposed new sanctions against Iran's Supreme Leader Ayatollah Ali Khamenei, in a televised speech, President Hassan Rouhani called the move "outrageous and idiotic."
Rouhani called the sanctions a sign that the Trump administration had "become mentally crippled." Earlier, Iran's Foreign Ministry spokesman Abbas Mousavi tweeted that the latest "useless sanctions" marked "the permanent closure of the path of diplomacy."
