The Syrian government rejected a report sent to the UN Security Council that blamed it for a chemical attack on the opposition-held town of Khan Sheikhoun in April in which dozens of people were killed, state media said on Friday.
"Syria rejects in form and substance what was included in the report of the UN and the Organization for the Prohibition of Chemical Weapons' Joint Investigative Mechanism (JIM) that was announced yesterday," state news agency SANA reported, citing an official in Syria's foreign ministry.
The official said the report had been compiled under instructions from the United States and other Western countries "to place more political pressure" on Syria, SANA reported.
The JIM report found Syrian President Bashar al-Assad's government responsible for the release of sarin at Khan Sheikhoun on April 4 this year.
The attack prompted a US missile strike against a Syrian air base which Washington said was used to launch the strike.
"(Damascus) condemns the reliance of the Joint Investigative Mechanism on the word of criminals who committed this immoral act in Khan Sheikhoun and those of suspect witnesses, as well as so-called open sources," a statement by the foreign ministry official said.
The official also said Syria renewed its commitment to the Organization for the Prohibition of Chemical Weapons and said it had no chemical materials restricted by the agreement.
Syria considered the use of chemical weapons "an immoral act, condemned everywhere, at any time, under any circumstance," SANA reported.
