I saw the OAN report in question and the short answer is no one. The reporter made it very clear that they were never approached by any one. They reporter and his support team picked out neighborhood people at random, as well as speaking with a number of medical care workers. Not one person said they were aware of any chemical attack, excepting the doctors, who made it clear that it was a staged propaganda false flag. They stated not one of the supposed attack victims presented actual symptoms of chemical exposure. The people near the city square where the attack was said to have occurred stated it was a hoax designed by the terrorists (rebels), who were being routed, in order to get Assad's forces off their backs so they could escape.
The video footage also showed piles and piles of weapons and explosives the rebels were forced to abandon, including a mortar factory with tens of thousands of mortars-in-production. The townspeople were all very greatful to the government for driving the jihadis away.
Similar reporting today from Robert Fisk at the UK Independent...neocon chickens coming home to roost.
