CNN reports: Iran will take part in a conference intended to hash out a solution to the Syrian conflict before the end of the year — if it receives an invitation, an Iranian official said Saturday, according to state-run media.

“Iran will do its best to help solve the issue through dialogue between the Syrian parties,” said Foreign Minister Mohammad Javad Zarif, according to the Iranian news agency IRNA.

Speaking at a joint news conference with Lakhdar Brahimi, the U.N. special envoy on Syria, Zarif said Tehran would participate in the Geneva talks to help end the war through political means.

Brahimi arrived Saturday in Tehran with a delegation on his second trip to Iran since he was appointed to the U.N. mission, according to state-run Press TV. He is on a Middle East tour aimed at raising support for the planned meeting.
