The same happened with /r/syriancivilwar back in 2014-2015, in that case it was even more depressing because you also had some nutjobs like ISIS directly involved in said conflict, which meant massacres like this one [1] getting reported almost in real time, with images from the place where it had all happened and all that. The 2014 fight between Russia and Ukraine was also heavily documented in almost real time.
