Iranian President Hassan Rouhani has "firmly condemned" terrorist bomb explosions in the Belgian capital city of Brussels, Press TV reported.
Posting a message on his Twitter account on Tuesday, the Iranian president offered his deepest condolences to the Belgian government and people, particularly those who lost their loved ones.
Earlier in the day, Iranian Foreign Ministry spokesman, Hossein Jaberi Ansari, also condemned the twin blasts in Brussels, stressing the importance of adopting all-embracing efforts to fight terrorism which is threatening the entire world.
"Repetition of terrorist operations in different parts of the world is an indicator of the common threat [posed] by terrorism and extremism to the entire world," Iranian Foreign Ministry spokesman, Hossein Jaberi Ansari, said on Tuesday.
He added that such terrorist incidents highlight the necessity of "integrated and overarching" action against the ominous phenomenon of terrorism as well as centers of political, ideological and financial support for terrorism.
A series of blasts hit Brussels' Zaventem airport and a city metro station, killing at least 34 people and injuring 230 others. The Belgian authorities are treating the explosions as part of a coordinated terrorist attack.
