Syria's opposition National Coalition has rejected an Iranian offer to broker talks with the Assad regime.
The opposition said that the bid was 'not serious' and called Tehran 'part of the problem'.
In a statement, the key opposition group said that the Iranian initiative is not serious and lacks political credibility.
According to Gulf News, the comments came after Iranian President Hassan Rouhani said his government was willing to 'facilitate dialogue' between the Syrian government and opposition fighters.
The Syrian opposition said it was skeptical that Iran, a staunch ally of President Bashar al-Assad, could broker talks.
The Syrian opposition has long alleged that Iran has sent military personnel to help al-Assad's forces in their fight against the rebels, the report added.
