Iranian anti-government protestors filled the streets of Tehran on Saturday after the Iranian government admitted that it allegedly mistakenly shot down a Kyiv-bound commercial airplane.

Videos of the protests show people in large numbers shouting, "Khamenei is a murderer!" according to The New York Times.

Ukraine International Airlines Flight 752 was shot down Wednesday shortly after leaving Imam Khomeini International Airport in Tehran by an Iranian surface-to-air missile. All 176 people on board — including Ukrainians, Iranians and Canadians — were killed.

Iranian Foreign Minister Mohammad Javad Zarif described the event as "human error at time of crisis caused by US adventurism" in a tweet.

A sad day. Preliminary conclusions of internal investigation by Armed Forces:



Human error at time of crisis caused by US adventurism led to disaster



Our profound regrets, apologies and condolences to our people, to the families of all victims, and to other affected nations. — Javad Zarif (@JZarif) January 11, 2020

The crash came just hours after Iran launched a retaliatory missile strike on two Iraqi military bases housing U.S. troops.

"The Islamic Republic of Iran deeply regrets this disastrous mistake. My thoughts and prayers go to all the mourning families," Iranian President Hassan Rouhani said Saturday, according to the Times.

Rouhani's apology wasn't enough to quell the protestors, though, as many shouted "Death to liars" and "Death to the dictator" in reference to Iranian Supreme Leader Ayatollah Ali Khamenei , according to the paper.

The voice of the Iranian people is clear. They are fed up with the regime’s lies, corruption, ineptitude, and brutality of the IRGC under @khamenei_ir's kleptocracy.
