The main Syrian opposition coalition said Sunday the delegation representing the opposition in the Geneva II conference would comprise all factions in and outside Syria.
"There is a tendency inside the coalition that most members of the delegations should be from outside the coalition," Fayez Sara, a political adviser to coalition leader Ahmad Jarba, told Anadolu Agency via phone.
"We do not monopolize the opposition as some people like to propagate," he said.
On Saturday, UN and Arab League Special Envoy to Syria Lakhdar Brahimi urged the Syrian opposition to submit the names of its delegation to Geneva II no later than December 27.
Sara said that the coalition's decision to attend the conference would not be affected by an invitation for Iran to attend.
"To us, Iran is an enemy, just like the regime of Bashar al-Assad," he asserted.
"If we are going to negotiate with the regime, why should not Iran attend?" Sara noted. "The regime and Iran are two sides of the same coin."
"We would not sit down with Iran directly during or after the conference," insisted the opposition official.
Geneva II, which will aim to find a political solution to the conflict in Syria, had initially been planned for late May, after having first been proposed at a Moscow meeting between US Secretary of State John Kerry and Russian counterpart Sergei Lavrov.
Amid heated disagreements as to who should have seats at the table, however, the event was subsequently postponed.
Syria has been in the throes of conflict since 2011 when a peaceful uprising against Assad escalated into a civil war following a violent government crackdown.
According to the UN, more than 100,000 people have been killed in the conflict so far.
The raids targeted positions of the Iran-backed Shiite rebels and their allies of renegade troops loyal to former president Ali Abdullah Saleh in Sanaa, the military officials and rebel media said.
