Dujarric made the remarks in his Wednesday noon's briefing with reporters.

Commenting on goals of the United Nations Special Envoy for Syria Staffan de Mistura upcoming trip to Iran, the spokesman said, “I think, ... Iran is one of the regional powers. They, like other regional powers, have influence at various parts — parties in this conflict. And I think the regional powers have a key role to play in putting the political dialogue back on track. So I think it's only normal that the Special Envoy consult with regional powers.”

Iran's Deputy Foreign Minister for Arab-African Affairs Hossein Amir-Abdollahian on Tuesday discussed latest developments in Syria in a phone conversation with de Mistura who said dialogues and consultations held in Geneva with various Syrian parties as well as world representatives including Iranian Ambassador and Deputy Permanent Representative to the UN Gholam Hossein Dehghani were positive and constructive.

Both sides underlined the importance of finding a political solution to end the Syrian crisis, he added.

De Mistura is scheduled to visit Iran for further consultations on Syrian crisis, within the framework of his regional tour.

Amir-Abdollahian, while emphasizing the continued support for the Syrian people and government in the fight against terrorism, said political solution is the only option to end crisis in Syria.
