Tunisia will propose a political solution to the Syrian crisis involving a peacekeeping force, Tunisian presidential spokesman Adnan Mancer said on Thursday, the Associated Press reports. The Yemen-style plan suggests that President Assad steps down. It will be presented at the “Friends of Syria” conference on Friday. \"Tunisia will propose a peacekeeping operation, to protect civilians,” Mancer said. Even though Russia and China will not join the conference he said there would be “an important role for Russia and China to convince the Syrian regime to leave power since it has lost all its legitimacy and a political and peaceful solution of the Syrian crisis is not possible with its presence.\" More than 70 countries have been invited to the conference which will start on Friday in the Tunisian capital, Tunis.
