Syrian National Coalition leader Moaz Alkhatib said on Sunday he was willing to hold talks with Bashar al-Assad's representatives in rebel-held areas in northern Syria.
The talks' objective would be to find a way for Assad to leave power with the "minimum of bloodshed and destruction", Alkhatib said in a statement published on his Facebook page.
"If the regime is so concerned about sovereignty and does not want to venture out of Syrian territories then there is a suitable solution, which is the liberated land in northern Syria," Alkhatib said.
"There is an important question. Will the regime agree to leave with the minimum of blood and destruction?"
Alkhatib, a moderate cleric in Damascus, last month offered to hold talks with Assad's ceremonial deputy Farouq al-Shara about an exit for Assad if the authorities started releasing tens of thousands of political prisoners jailed since the eruption of the 22-month uprising.
