UNITED NATIONS (AP) -- The U.N. envoy on Syria has launched his latest effort to bring that country's parties together toward a long-elusive agreement to end the conflict there.
Staffan de Mistura on Tuesday announced the heads of four "working groups" on key issues ahead of his discussions in the coming days on the sidelines of the U.N.'s annual gathering of world leaders.
De Mistura is expected to meet with the five permanent members of the U.N. Security Council and the U.N. secretary-general on a way forward amid a Syrian refugee crisis and new Russian military moves in Syria.
The groups will hold simultaneous discussions among Syrian parties on safety and protection of civilians; political and constitutional issues; combatting terrorism and military and security issues; and reconstruction and development.
A European leads each group.
