"Iran has repeatedly announced since the very beginning of the ongoing crisis in Syria that the problem should be solved through diplomatic solutions. Any solution to the crisis should guarantee the Syrian people's right to determine their own destiny based on Syrian-Syrian talks," said the spokeswoman.
Criticizing Kerry's proposal for Iran's sidelined participation in the International Geneva II Peace Conference, Afkham said Tehran would only accept the proposals which are in line with its dignity.
On Sunday, John Kerry suggested that Iran could play a sideline role in the Syrian peace talks.
He said that it would be difficult to see how Iran could be a ministerial partner in the Geneva II talks. However, he said that Tehran could play a helpful role in finding a solution to the conflict in Syria.
Kerry suggested that Iran’s diplomatic office in Geneva might be able to help as an unofficial participant.
Iran has always underlined a negotiated end to the crisis in Syria, reiterating that a halt in the arms flow to anti-government militants is the prerequisite to any diplomatic solution to the Syrian problem.
In November 2012, Iran hosted a meeting between the representatives of the Syrian government and opposition to encourage them to start talks to find a political solution to their problems. The National Dialogue Conference kicked off work in Tehran mid November with the motto of 'No to Violence, Yes to Democracy".
The meeting brought together almost 200 representatives of various Syrian ethnicities, political groups, minorities, the opposition, and state officials.
The conflict in Syria started in March 2011, when sporadic pro-reform protests turned into a massive insurgency following the intervention of western and regional states.
The unrest, which took in terrorist groups from across Europe, the Middle-East and North Africa, has transpired as one of the bloodiest conflicts in recent history.
As the foreign-backed insurgency in Syria continues without an end in sight, the US government has boosted its political and military support to Takfiri extremists.
Washington has remained indifferent to warnings by Russia and other world powers about the consequences of arming militant groups.
