Protests have erupted in Iran against the Ayatollah Khamenei regime as members of the public express outrage over the country’s admitted downing of an Ukrainian jetliner carrying 176 people, many of them Iranians.

You can see photos and videos from the January 11, 2020 protests throughout this article. How big are the protests? “Hundreds” of people were protesting against the regime, according to The Times of Israel. CNN reported that the protesters numbered in the thousands.

The British ambassador in Tehran, Robert Macaire, was detained but released at the protests, according to Radio Farda.

President Trump responded with a tweet written in Persian (Farsi), which translated as saying, “To the brave, long-suffering people of Iran: I’ve stood with you since the beginning of my Presidency, and my Administration will continue to stand with you. We are following your protests closely, and are inspired by your courage.”

Trump followed that up with a second tweet in Persian, also known as Farsi:

دولت ایران باید به گروه‌های حقوق بشر اجازه بدهد حقیقت کنونی اعتراضات در جریان مردم ایران را نظارت کرده و گزارش بدهند. نباید شاهد کشتار دوباره ی معترضان مسالمت آمیز و یا قطع اینترنت باشیم. جهان نظاره گر این اتفاقات است. — Donald J. Trump (@realDonaldTrump) January 11, 2020

He wrote in English, “The government of Iran must allow human rights groups to monitor and report facts from the ground on the ongoing protests by the Iranian people. There can not be another massacre of peaceful protesters, nor an internet shutdown. The world is watching.”

Hadi Ghaemi, executive director of Iran Human Rights.org, an organization which documents human rights abuses in the country, wrote on Twitter. “Today’s protests as well as November’s mass uprising shows Iranian people are fed up with their leaders’ never ending pattern of incompetence, lies, and coverups at all levels. Potentials of generation after generation squashed. #IranProtests.”

4. Iranians Formed the Largest Group of Passengers on the Doomed Flight, Which Iran Now Admits Shooting Down

Ukraine’s Foreign minister has said that 82 Iranians and 63 Canadians were on board the Ukraine International Airlines Flight 752, which was headed from Tehran to Kiev, when Iran shot it down. According to BBC, other victims included people from Ukraine, Afghanistan, Great Britain, and Germany.

BBC reports that, since Iran said 147 people on the plane were Iranian, many people on board might have held dual nationalities.

FARS, which is Iran’s semi-official news agency, wrote, “The General Staff of the Iranian Armed Forces said in a statement on Saturday that the Ukrainian Boeing 737 plane was shot down as a hostile object due to human error at a time of heightened US threats of war.”

The story added: “An expert investigation by the General Staff of the Iranian Armed Forces after the Ukrainian airline company’s Boeing 737 incident has found that flight 752 of the Ukrainian airlines has been shot down as a hostile flying object that was approaching a sensitive IRGC center and was shot down due to human error few hours after Iran’s missile attack on the US and as Iran’s military was expecting attacks by the US army.”

Armed Forces’ internal investigation has concluded that regrettably missiles fired due to human error caused the horrific crash of the Ukrainian plane & death of 176 innocent people.

Investigations continue to identify & prosecute this great tragedy & unforgivable mistake. #PS752 — Hassan Rouhani (@HassanRouhani) January 11, 2020

Iranian President Hassan Rouhani said in a statement: “Armed Forces’ internal investigation has concluded that regrettably missiles fired due to human error caused the horrific crash of the Ukrainian plane & death of 176 innocent people. Investigations continue to identify & prosecute this great tragedy & unforgivable mistake. The Islamic Republic of Iran deeply regrets this disastrous mistake. My thoughts and prayers go to all the mourning families. I offer my sincerest condolences.”

He added, in a statement posted to his official Twitter account: “The tragedy of the stampede at Gen. Soleimani’s funeral in Kerman and the crash of a Ukrainian passenger plane in Tehran that killed numerous Iranians, including a group of students, as well as other nationalities, deeply saddens all Iranians. May they rest in peace.”

Iran’s armed forces headquarters released this statement, according to CNN: “The aircraft came close to a sensitive IRGC military center at an altitude and flight condition that resembled hostile targeting. Under these circumstances, the aircraft was unintentionally hit, which unfortunately resulted in death of the many Iranian and foreign nationals.”

Javad Zarif, Iran’s foreign minister, wrote on Twitter, “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. ?”

Tasnim News Agency wrote on Twitter, “#British ambassador to #Tehran has been detained for organizing suspicious movements and protests in front of Amir Kabir University but released after hours and will be summoned by foreign ministry tomorrow morning.”

Rahbord-e Moaser, described by Radio Farda as “a hardliner website,” reported that Macaire was arrested for supposedly “instigating the crowd and taking photos of the protest”.

Foreign Secretary Dominic Raab said in response, “The arrest of our Ambassador in Tehran without grounds or explanation is a flagrant violation of international law. The Iranian government is at a cross-roads moment. It can continue its march towards pariah status with all the political and economic isolation that entails, or take steps to deescalate tensions and engage in a diplomatic path forwards.”
