I read about it in an article here at FR posted yesterday, but the article was scant on specifics. I don’t know when he was killed, how, or otherwise, just that he was killed according to the article. Then I read other articles indicating support for Erdogan was superior to that of the support for the army. Several different articles, therefore it seemed true to me.
I wasn’t questioning the truth of it, just trying to understand the context. I heard that Erdogan purged a couple of hundred generals and admirals in recent years.
