DUBAI (Reuters) - Iran said on Tuesday it had arrested people accused of a role in shooting down a Ukrainian airliner and had also detained 30 people involved in protests that have swept the nation since the military belatedly admitted its error.
Wednesday’s shooting down of Ukraine International Airlines flight 752, killing all 176 people aboard, has led to one of the biggest public challenges to Iran’s clerical rulers since they took power in the 1979 Islamic revolution.
In a step that would increase diplomatic pressure, Britain, France and Germany launched a dispute mechanism to challenge Iran for breaching limits on its nuclear programme under an agreement which Washington abandoned in 2018.
In the 10 days since the United States killed Iran’s most powerful military commander in a drone strike, Tehran has faced escalating confrontation with the West and unrest at home, both reaching levels with little precedent in its modern history.
It shot down the airliner on Wednesday during a period of high alert, hours after it had fired missiles at U.S. targets in Iraq. After days of denying a role in the crash, it admitted it on Saturday, calling it a tragic mistake.
Protesters, many of them students, have since held daily demonstrations chanting “Clerics get lost!” and called for the removal of Supreme Leader Ayatollah Ali Khamenei, in power for more than 30 years.
Police have responded to some protests with a violent crackdown, video posts on social media showed. Footage showed police beating protesters with batons, wounded people being carried, pools of blood on the streets and the sound of gunfire.
Iran’s police denied firing at protesters. The judiciary said 30 people had been detained in the unrest but said the authorities would show tolerance towards “legal protests”.
The full extent of the unrest is difficult to assess because of limits on independent reporting.
President Hassan Rouhani promised a thorough investigation into the “unforgivable error” of shooting down the plane, in a television address on Tuesday, the latest in a series of apologies from a leadership that rarely admits mistakes.
Judiciary spokesman Gholamhossein Esmaili said some of those accused of having a role in the plane disaster had been arrested, although he did not say how many or identify them.
Most of those on board the flight were Iranians or dual nationals. Canada, Ukraine, Britain and other nations who had citizens on the plane have scheduled a meeting on Thursday in London to consider legal action against Tehran.
The disaster and subsequent unrest comes amid one of the biggest escalations between Tehran and Washington since 1979.
Missiles launched at a US base in Iraq killed an American contractor in December, an attack Washington blamed on an Iran-backed group. Confrontation eventually led to the US drone strike on Jan 3 that killed Qassem Soleimani, architect of Iran’s regional network of proxy militias.
Iran’s government was already reeling from the reimposition of sanctions by the United States, which quit an agreement with world powers under which Tehran would secure sanctions relief in return for scaling back its nuclear programme.
Since Washington withdrew, Tehran has stepped back from its nuclear commitments, culminating this month with an announcement that Iran would no longer recognise limits on its production of enriched uranium. After months of threatening to act, European signatories to the deal, France, Britain and Germany, activated the agreement’s dispute mechanism on Tuesday.
