CAIRO (Reuters) - Syrian National Coalition President Ahmad Jarba said on Sunday the opposition would not attend proposed peace talks in Geneva unless there was a clear timeframe for President Bashar al-Assad to leave power.

"We have decided not to enter Geneva talks unless it is with dignity, and unless there is a successful transfer of power with a specific timeframe, and without the occupier Iran at the negotiating table," Jarba told an Arab League emergency meeting in Cairo.
