I'm not sure we really know that for sure either way... sure there are various statements by people in power etc.. however that hasn't seemed to have changed the situation on the ground yet
the more interesting bit of information are the jet shooting the helicopter for example, whether that was another part of the military opposing the coup or something else... the PM has made statements re: all planes currently flying over Ankara will be shot down which implies that they're all pro-coup
You are correct. Like I said before, there is much information and misinformation flying around.
It's going to be quite telling where Erdogan pops up.
