ST PETERSBURG, Russia - President Vladimir Putin on Friday defended Russian arms deals with Syrian President Bashar Assad's government and said the West should not send weapons to rebel forces that include "terrorist" groups."If the United States ... recognises one of the key Syrian opposition organizations, al-Nusra, as terrorist ... how can one deliver arms to those opposition members?" Putin said during a panel appearance with German Chancellor Angela Merkel at a Russian economic forum. "Where will (those weapons) end up? What role will they play?"
