UN chief Ban Ki-moon has invited Iran to take part in preliminary Syrian peace talks this week in Switzerland.
Mr. Ban yesterday said that Iran’s Foreign Minister Mohammad Javad Zarif had pledged that Tehran will play a positive and constructive role in securing a transitional government.
But Syria’s main opposition group said it would withdraw from the talks unless Mr Ban retracted the offer to Iran.
The preliminary talks will open in Montreux on Wednesday and then continue in Geneva two days later.
Syria’s government agreed to attend the meeting. The three-year conflict in Syria has claimed the lives of more than one lakh people.
An estimated two million people have fled the country and some 6.5 million have been internally displaced.
