Foreign Ministry spokesman Bahram Qasemi says collective efforts on behalf of the international community are crucial to containing extremist violence.
He made the remark in a statement carried by IRNA on Wednesday, referring to the Tuesday night terrorist attacks in Turkey which killed at least 41 people and injured 239.
In the deadliest bombings in a series of attacks this year in Turkey, three suicide bombers opened fire and blew themselves up in the third-busiest European airport, Istanbul's Ataturk.
No group has claimed responsibility for the latest massacre, but Turkish officials said after a preliminary investigation that signs point to the so-called Islamic State militant group.
Condemning the attack and offering condolences to Turkish nationals, Qasemi reiterated Iran's readiness for engagement with other regional states to deal with the scourge of extremism.
Foreign Minister Mohammad Javad Zarif, in a tweet on Wednesday, said the new attacks in neighboring Turkey are another proof that extremism is a "global threat".
"Terror rears its ugly head yet again in our friend and neighbor's airport. Extremist violence is a global threat; we must confront it together," he wrote.
Undue Interference
Spokesman for the Majlis National Security and Foreign Policy Commission Seyyed Hossein Naqavi Hosseini told ICANA that to prevent similar attacks in the future, he believes Turkey should contribute more actively to the global campaign against terrorism and its backers.
"Turkey should reverse its wrong policies," he said, pointing to Turkey's "undue interference in Syria" and its support for militant groups fighting to topple the Syrian government.
Naqavi Hosseini said Turkish officials were often warned by Tehran that if groups like IS become powerful, no one will be spared from their attacks.
"Ankara need to realize that terrorism is a threat to all."
