In Iran's first official comment after the fall of Bashar al-Assad's regime, Tehran called for an end to military conflicts and the start of a national dialogue with everyone's participation.

An Iranian Foreign Ministry statement said on Sunday that Tehran calls for “an immediate end to military conflicts, the prevention of terrorist acts, and the start of a national dialogue with the participation of all segments of Syrian society.”

She added that she "will spare no effort in helping to establish security and stability in Syria," and that she "will continue its consultations with all influential parties, especially in the region."

Tehran, which was Assad's ally in suppressing his people for years, said that it continues to support international mechanisms, especially Security Council Resolution 2254, to continue the political process in Syria.

She expected that “long-term and friendly relations between the Iranian and Syrian peoples will continue on the basis of a wise and far-sighted approach by the two countries.”

It considered that the future of Syria and decisions regarding its fate rest with the Syrian people alone, and that it “respects Syria’s unity and national sovereignty.”

The Iranian-backed militias contributed to saving Assad from the uprising that nearly brought down his rule about 10 years ago.

Syrian opposition fighters announced the overthrow of Assad after taking control of Damascus on Sunday, ending his family's rule of the country with an iron fist after a civil war that lasted more than 13 years.

Two senior Syrian officials told Reuters on Sunday that Assad had left Damascus for an unknown destination.

The Syrian Observatory for Human Rights said that Assad left the country through Damascus Airport.

Assad remained in Damascus until Saturday, according to Syrian and Arab security officials who spoke to the Wall Street Journal. Last week, his wife and children traveled to Russia, while his in-laws traveled to the United Arab Emirates.
