AP � High-level diplomats from Iran, Russia and Turkey are meeting with the U.N. envoy for Syria about creating a committee to revise the war-battered country�s constitution.

Tuesday�s talks in Geneva under U.N. envoy Staffan de Mistura come amid concerns he and other U.N. officials have expressed about a looming battle for Idlib. The northern city of nearly 3 million civilians is the last remaining rebel stronghold in Syria after 7-1/2 years of war.

Hossein Jaberi Ansari, a special envoy for Iran�s foreign minister, said a �good result� could emerge from the latest talks in Geneva.

President Vladimir Putin�s special envoy for Syria, Alexander Lavrentiev, declined on his way into the talks to say whether Russia would stop its airstrikes.
