"And saying, 'we are only going after chemical weapons areas, ' ignores the enormity of the problem", he said. "But I think he will have to look at the situation", Haley told the CNN host when asked whether Trump "wants tougher sanctions on Russian Federation and Iran".
Yesterday, Syrian Foreign Minister Walid Muallem repeated the government's denial that it used chemical weapons on Khan Sheikhun at dawn, saying warplanes had instead targeted a jihadist warehouse.
