The conference comes after an international agreement to launch talks between government and opposition by Jan.1

A Saudi government official said the conference is expected to take place on December 15.

International talks were held in Vienna last week in which countries involved, including Saudi Arabia, Iran, Turkey and the five permanent members of the U.N. Security Council, laid out a plan including formal talks between the government and opposition by Jan. 1.

Diplomatic sources said after those talks that Saudi Arabia, which backs Syria’s insurgents seeking to topple Syrian President Bashar al-Assad, would hold a conference to unite the political opposition there.
