Syria on Friday slammed Washington’s claims that it had used chemical weapons in its fight against rebels, accusing the United States of "lies" based on "fabricated information"."The White House published a statement full of lies about the use of chemical weapons in Syria, based on fabricated information, through which it is trying to hold the Syrian Government responsible for such use," State news agency SANA quoted a Foreign Ministry Official as saying.The official said the US claims came "after reports affirming that armed terrorist groups active in Syria are in possession of deadly chemical weapons and the technology necessary to make them". Washington said yesterday there was evidence that the Syrian Government had used chemical weapons including sarin nerve gas in attacks killing 150 people.
