Walid al-Moallem, addressing world leaders at the U.N. General Assembly in New York, also charged that the U.S., Britain and France had blocked the naming of the real perpetrators of chemical weapons attacks in Syria.
He claimed "terrorists" fighting the regime in the civil war are being supplied with chemical weapons, but he did not name specific nations accused of supplying them.
President Barack Obama told the UN last week that it was the President Bashar Assad's regime that was behind a chemical weapons attack in August that killed hundreds in the Damascus suburbs and brought threats of a US strike.
