In the hours after the attack, the prime minister convened an emergency meeting of the Ministerial Council for National Security, which issued a statement condemning the attack and announcing an investigation into why the security forces did not prevent the PMF supporters from entering the building, NRT reported.

It added that fifteen people have already been arrested in connection with the attack, though it did not provide any details about their identities or affiliations.

Calling the attack “unacceptable,” Kadhimi warned in a tweet against a “return to sectarian rivalry or an Iraqi against another for political purposes.”

“We passed that hurdle together, and we will not go back,” he added.

In a statement published late on Saturday, State Department Spokesperson Morgan Ortagus also condemned the attack, saying “The ability to speak freely and critically is a vital component of any democracy, and political parties should be able to engage in robust debate without threat from militias and thugs.”

“The destabilizing activities of Iran-backed militias operating outside of Government of Iraq control are inflaming ethnic and sectarian tensions and undermining democracy,” the US official claimed.

Meanwhile, UN Assistance Mission for Iraq (UNAMI) said in a tweet that “We express our grave concern about burning of Kurdistan Region flag and attack on KDP offices in Baghdad. Acts of violence and intimidation (never a solution to disagreement!) are to be condemned,”

“Iraq needs unity, stability and dialogue to tackle its many problems.” It added.

“Sad and worrying events targeting Baghdad KDP office. Violence cannot be a means of expression,” European Union Delegation to the Republic of Iraq said in a tweet.
