WASHINGTON: US defense secretary James Mattis has said Friday that chlorine gas has been weaponized and used repeatedly by the Syrian government.
Mattis said to reporters that the Assad regime would be ill advised to “go back to violating the chemical weapons convention.” Mattis added that he has not seen evidence of use of sarin gas by Syrian government but is concerned and looking into reports from the ground.
