U.S. Ambassador has repeated false accusations against Syrian government in the U.N. Security Council Meeting on Syria's Chemical Weapons.

"The U.N.'s failure to hold Syria accountable for its use of chemical weapons has made the world "a far more dangerous place", US Ambassador to the United Nations Nikki Haley claimed on Wednesday.

The U.S. Ambassador told the Security Council that its lack of action on Syria has led others to take notice, pointing to the use of nerve agents against North Korean leader Kim Jong Un's half-brother in Malaysia and the poisoning of a former spy and his daughter in England.

The Syrian government fiercely denied using or even possessing chemical weapons since the country’s compliance with the Chemical Weapons Convention was certified by international observers in 2013, as the world is still waiting for the US and its allies to provide any proof for its claims of Bashar al-Assad government's involvement in the alleged chemical attack.

Syrian President Bashar al-Assad had characterized the alleged chemical attack in Khan Sheikhoun as a provocation to justify the US strike on Shayrat airbase in Homs province.

The Syrian leader had also warned of the possibility of the new provocations similar to the one in Idlib.
