“The Islamic Republic strongly condemns any measure that endangers the lives of innocent people,” the ministry’s spokesman, Ramin Mehmanparast, said on Tuesday.

Mehmanparast described the deadly incident as a "source of sorrow," and called for greater global efforts to eradicate terrorism.

“We believe all governments must try to maintain calm and security for everyone. Acts of extremism and terrorism have to be uprooted across the world and no effort should be made to justify violence,” he stated.

The official criticized some politicians and governments who at points support extremist groups for their own political benefits.

“Allowing terrorist groups to operate, and delisting them from the blacklist of terrorist organizations under the pretext of supporting freedom will eventually lead to instability and disorder, and will affect all people,” he warned.

Tehran has repeatedly criticized the Western governments for backing the anti-Iran terrorist Mujahedin-e Khalq Organization (MKO).

In December 2012, Canada dropped the MKO from its blacklist of terrorist organizations, following similar moves by the United States and the European Union.

The MKO is responsible for numerous acts of terror and violence against Iranian civilians and officials. Thousands of Iranians have fallen victim to the acts of terror carried out by the MKO since the victory of Iran's Islamic Revolution in 1979.
