U.S. Ambassador to the United Nations Nikki Haley said that the U.N. Security Council will hold a meeting on Friday on the situation in Syria’s Idlib province. 

Haley warned Syria’s government not to use chemical weapons ahead of a widely expected military offensive there.

“This is a tragic situation, and if they want to continue to go the route of taking over Syria, they can do that,” Haley said at a news conference, referring to the government of Syrian President Bashar al-Assad as well as its allies Russia and Iran.

“But they cannot do it with chemical weapons. They can’t do it assaulting their people and we’re not going to fall for it,” she added.

Haley reiterated what President Trump had said: “If there are chemical weapons that are used, we will act accordingly"
