The Swedish Foreign Ministry has expressed deep regret for the recent attack on the Iranian embassy near Stockholm, promising to adopt severe measures against the culprits,reported Press TV.
Sweden will strictly counter those who encourage individuals and groups to carry out violent acts such as entering an embassy without permission under the pretext of expressing their political views, two officials at the ministry said in a meeting with the Iranian ambassador to Sweden, Rasoul Eslami, on Monday.
The ministry vowed to completely pay for the damage inflicted on the Iranian embassy.
The Iranian embassy in Sweden came under attack on Friday when more than 150 people gathered outside its main building to protest the outcome of the June 12 presidential election.
One of the embassy personnel was seriously injured in the attack, police said.
After a crowd of 200 protesters attacked the embassy, Iran's Foreign Ministry summoned Sweden's ambassador to Tehran, Christofer Gyllenstierna, to express its severe discontent over the incident.
Eslami said earlier that members of the terrorist Mujahedin Khalq Organization (MKO) were found to be among the assailants.
According to Iranian security officials, arrested members of the group had confessed that they were extensively trained at their bases in Iraq's Camp Ashraf to create post-election mayhem in the country.
The officials said they discovered that the MKO terrorists had helped intensify the violence in Iran after the victory of President Mahmoud Ahmadinejad in the June 12 vote.
At the Monday meeting, Eslami called for an immediate recognition of the attack as a terrorist act which runs counter to international regulations and conventions.
Following Ahmadinejad's victory, Iran became the scene of rallies with defeated candidates Mir-Hossein Mousavi and Mehdi Karroubi rejecting the result as fraudulent and demanding a re-run.
