Iranian authorities say anti-Iran terrorist group MKO has been involved in the recent attack on the Iranian embassy near Stockholm in Sweden. 
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.
Rasoul Emami, Iranian Ambassador to Sweden, said members of the terrorist Mujahedin Khalq Organization (MKO) were found to be among the assailants.
According to Emami, the terrorists have been caught on camera smashing the windows, breaking through the building, attacking embassy staff and tearing down the fence.
The remarks come only a week after Iranian security officials discovered that the terrorist Mujahedin Khalq Organization (MKO) had helped intensify the post-election violence in Iran.
According to the security officials, the arrested members had confessed that they were
extensively trained at their bases in Iraq’s camp Ashraf to create post-election mayhem in the country.
Founded in the 1960s, MKO is a guerilla group, which masterminded a slew of terrorist operations in Iran.
The terrorists are especially notorious for taking sides with former dictator Saddam Hussein during the war Iraq imposed on Iran (1980-1988).
The group masterminded a slew of terrorist operations in Iran and Iraq — one of which was the 1981 bombing of the offices of the Islamic Republic Party, in which more than 72 Iranian officials were killed.
A 2007 German intelligence report from the Federal Office for the Protection of the Constitution has identified the MKO as a "repressive, sect-like and Stalinist authoritarian organization which centers around the personality cult of [MKO leaders] Maryam and Masoud Rajavi".
Banisadr. I had no idea about the "ideological marriage"! In 1981, when the office of MKO in Iran was shutdown, I was studying at school and I was completely unaware of activities of the organization. At high school I expressed some sort of opposition. For Example I complained about inspecting students’ bags at schools or why they forced the students to take part in group prayers. These were my challenges against the regime. In fact, I didn’t have enough knowledge about MKO in the way that I could arrange my activities along with their goals. Basically, all the information I could get about MKO, Masud and Maryam Rajavi, and the Ideological Revolution was in 1985 and 1986 when I arrived into the organization. When I entered into the group, I started knowing about the elevations in their movements.
