The streets of Tehran were filled with outraged Iranians demanding the resignation of Ayatollah Ali Khamenei after news that Iran shot down the Ukrainian passenger plane by mistake. Vigils were held near Amir Kabir University, but the crowd became angry quickly.

The plane carrying 176 people was shot down after Iran launched missiles on Iraq military bases used to house U.S. troops. Some experts questioned why officials did not close off the airspace to civil aviation. There were 10 flights departing from the Tehran airport midnight through the departure of the Ukrainian airline, according to FlightRadar24.

For three days, Iran officials denied shooting down the jetliner, and later, bulldozers were seen clearing up debris from the crash site in what appeared to be an effort to cover up what happened.

Iran’s authorities were told on Wednesday about the strike on the plane by Revolutionary Guards aerospace commander Brig-Gen. Amir Ali Hajizadeh, which raises questions why Iran didn’t admit to the mistake earlier.

In a press conference, Hajizadeh said, “I take full responsibility and I will obey whatever decision is taken. When I found out what had happened, I wanted to die. I said, I would rather die rather than be a witness to such an incident.”

Videos posted to social media show protesters in front of Tehran’s Amir Kabir University chanting, “Commander-in-chief (Khamenei) resign, resign.” Protesters are heard in other videos shouting “Shame on you Khamenei, leave the country,” “death to the liars,” and “shame on the Revolutionary Guards, let the country go.”

Iranian journalist Masih Alinejad tweeted a video of the protests and wrote, “Protests erupt against the Revolutionary Guards at Amir-Kabir University in Tehran due to authorities’ incompetence and negligence after the recent plane crash that killed more than 176 people. Some people had claimed Iranians were united after #Soleimani’s death. Think again.”
