WASHINGTON (AP) — American officials say Russia has rejected intelligence the U.S. has provided suggesting Syrian President Bashar Assad's regime has used chemical weapons on its own people.
The officials say the U.S. sent a diplomatic delegation to Moscow last month to show evidence of Syrian chemical weapons use.
But they say the information failed to convince Russian officials and prompted no change in the Kremlin's support for Assad.
Russia's rejection would further put into question claims of a new spirit of U.S.-Russian cooperation to end Syria's two-year civil war. The former Cold War foes say they're trying to get Syria's government and opposition into peace talks, even as Russia continues providing Assad with military aid.
The officials spoke on condition of anonymity because they weren't authorized to speak publicly on the matter.
