A group of Iranian protesters demanded Iran's Supreme Leader Ayatollah Ali Khamenei, the top authority in the Islamic Republic, step down on Saturday after Tehran said that its military had mistakenly shot down a Ukrainian plane, killing all 176 people on board.
"Commander-in-chief (Khamenei) resign, resign," videos posted on Twitter showed hundreds of people chanting, in front of Tehran's Amir Kabir university. Reuters could not verify the authenticity of the video footage.
Also, a leader of Iran's opposition Green Movement, Mehdi Karroubi, called on the Supreme Leader to step down over the handling of the shooting down of the Ukrainian airliner.
In a statement posted online, Karroubi asked when Khamenei was told about the shooting down of the plane after it took off from Tehran on Wednesday, and why there had been a delay in informing the public about the real reasons for the crash.
