A senior Iranian official says President Bashar Assad has a "pivotal" role to play in the war on terrorism and in resolving Syria's devastating four-year conflict. Deputy Foreign Minister Hossein Amir Abdollahian said after meeting with Assad on Thursday that any "successful" attempt to find a solution should take into consideration the right of the Syrian people to shape their future. Iran is a key backer of Assad and has said it is working on a four-point initiative to end the Syrian civil war. Abdollahian met earlier in the week with U.N. special envoy to Syria Staffan de Mistura while on a trip to neighboring Beirut.
