The United States is preparing new sanctions against Russia over its continued support of Syrian President Bashar-al Assad, the US ambassador to the United Nations, Nikki Haley, says.
In an interview with CBS' Face the Nation, Haley said that the sanctions would be announced on Monday by Treasury Secretary Steven Mnuchin.
"They will go directly to any sort of companies that were dealing with equipment related to Assad and chemical weapons use," Haley said on Sunday.
She also ruled out any one-on-one talks between the US and Assad.
Haley said Syria had so far refused to take part in multilateral negotiations as part of a political process facilitated by the United Nations, adding that Russia should "deliver" Syria to the negotiating table.
But she said Syria was not "worthy" of direct talks with Washington: "We are not going to have any one-on-one talks with Assad."
