Iraq told Sweden it would sever diplomatic ties if a holy Quran is burned again, after hundreds of people stormed the Swedish embassy in Baghdad and set it alight in a protest against plans for one to be burned in Stockholm later on Thursday.

Swedish Foreign Minister Tobias Billstrom said embassy staff were safe but that Iraqi authorities had failed in their responsibility to protect the embassy in accordance with the Vienna Convention.

The Iraqi government strongly condemned the burning of the Swedish embassy, according to a statement from the office of Iraqi Prime Minister Mohammed Shia Al-Sudani which declared it a security breach and vowed to protect diplomatic missions.

But Baghdad had also “informed the Swedish government … that any recurrence of the incident involving the burning of the holy Quran on Swedish soil would necessitate severing diplomatic relations”, the statement said.

Billstrom said what happened was “completely unacceptable and the government strongly condemns these attacks”. He added: “The government is in contact with high-level Iraqi representatives to express our dismay.”

Thursday’s demonstration was called by supporters of influential cleric Muqtada al-Sadr to protest against the second planned Quran burning in Sweden in weeks, according to posts in a popular Telegram group linked to the cleric and other pro-Sadr media.

Sadr, one of Iraq’s most powerful figures, commands hundreds of thousands of followers, whom he has at times called to the streets, including last summer when they occupied Baghdad’s heavily fortified Green Zone and engaged in deadly clashes.

Sadr said in a tweet on Thursday that the Iraqi government should not resort only to condemnation and must take a firm position.

“I will wait for the firm official response before any action of my own,” Sadr tweeted.

Finnish news agency STT reported that the Finnish embassy, which is in part of the same enclosure as the Swedish, had also been evacuated but that staff were safe and unhurt.

Swedish police on Wednesday granted an application for a public meeting outside the Iraqi embassy in Stockholm on Thursday, the police permit showed, and two people were expected to participate.

Swedish news agency TT reported that the two planned to burn the Quran and the Iraqi flag at the public meeting, and the duo included a man who had set a Quran on fire outside a Stockholm mosque in June.

Swedish police denied several applications earlier this year for protests that were set to include burning the Quran, citing security concerns. Courts have since overturned the police’s decisions, saying such acts are protected by the country’s far-reaching freedom of speech laws.

The Swedish government said this month it is considering changing the law to allow police to stop people from setting the Quran on fire in public if they endangered Sweden’s security.

A series of videos posted to the Telegram group, One Baghdad, showed people gathering around the Swedish embassy around 1 a.m. on Thursday (2200 GMT on Wednesday) chanting pro-Sadr slogans and storming the embassy complex around an hour later.

“Yes, yes to the Quran,” protesters chanted.

Videos later showed smoke rising from a building in the embassy complex and protesters standing on its roof.

Quran protests 

Iraq’s foreign ministry also condemned the incident and said in a statement the Iraqi government had instructed security forces to carry out a swift investigation, identify perpetrators and hold them to account.

By dawn on Thursday, security forces had deployed inside the embassy and smoke rose from the building as firefighters extinguished stubborn embers, according to Reuters witnesses.

Iraqi security forces later charged at a few dozen protesters still milling around outside the embassy in an attempt to clear them from the area. Protesters had earlier briefly thrown rocks and projectiles towards the large number of security forces gathered.

Late last month, Sadr called for protests against Sweden and the expulsion of the Swedish ambassador after the Quran burning in Stockholm by an Iraqi man.

After the burning, the man was reported to police for agitation against an ethnic or national group. In a newspaper interview, he described himself as an Iraqi refugee seeking to ban the Quran.

Two major protests took place outside of the Swedish embassy in Baghdad in the aftermath of that Quran burning, with protesters breaching the embassy grounds on one occasion.

The governments of several Muslim countries, including Iraq, Türkiye, the United Arab Emirates, Jordan and Morocco issued protests about the incident, with Iraq seeking the man’s extradition to face trial in the country.

The United States also condemned it but added that Sweden’s issuing of the permit supported freedom of expression and was not an endorsement of the action.
