Syria: United States suspects the regime of a new chemical weapons attack

Has Bashar al-Assad's regime carried out a new attack on chemical weapons? The United States has reported "indications" that suggest it, Tuesday, May 21. In a statement, the US State Department mentions an "alleged chlorine attack in northwestern Syria on the morning of May 19". And threat of retaliation.
The State Department says the "alleged chlorine attack" would have taken place on May 19. The Syrian Observatory for Human Rights and the White Helmets say they have no evidence of such an attack.
"We are still gathering information on this incident," US Foreign Ministry spokeswoman Morgan Ortagus said.
In contrast, the Syrian Observatory for Human Rights (OSDH), which has an extensive network of sources in Syria, has "documented no chemical attack in the mountains of Latakia" and has "no evidence ", said his director, Rami Abdel Rahmane, to AFP. "There were no civilians in the region", only jihadists, he also assured, which complicates the independent verification of a possible chemical attack.
The White Helmets, rescuers who have reported several chemical attacks in the past, also told AFP they did not have "for the moment any information on this attack".
