Arab League chief Nabil al-Arabi on Sunday welcomed a US-Russian deal to remove Syria's chemical weapons, saying it will help to find a political solution to the war.

The deal "is a step closer to a political solution," Arabi said in a statement.

On Saturday, US Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov announced an agreement to eliminate Syria's chemical arms stockpile, after three days of talks in Geneva.
