Syria's regime is prepared to discuss the creation of a new unity government at peace talks in Geneva but President Bashar al-Assad's fate remains off limits, its lead negotiator told AFP Tuesday.

Assad's chief representative in Geneva, UN ambassador Bashar al-Jafaari, had during previous rounds of peace talks insisted that any discussion of a political transition in Syria was premature.

"A broader unity government is the only topic of discussion here," Jafaari said in the interview with AFP.

"It is not in our jurisdiction, it is not within our prerogatives to discuss the fate of President Bashar al-Assad."
