I don’t know whether hospitals were hit by airstrikes, or whether, if damaged, it was a result of tank, artillery, or mortar fire. It’s not impossible that Russian airstrikes hit a medical facility, but no purportedly international group like the Red Cross or MSF has made that accusation.
The RFL/RL link you cite is interesting. Do you notice how it refers to claims of “opposition sources in Syria.” Also, to “[t}head of the opposition controlled Free Health Directorate of Aleppo.” And, to “[t]he pro-opposition Shaam News Network and other opposition sources.”
“Opposition” is apparently a euphemism for the terrorist jihadis on whose word we rely but can’t say so directly.
Also, the article refers suspiciously to “field hospitals,” which might be a tent with a first aid kit and a medic in it, not a permanent dedicated facility.
The article also cites the Institute for Study of War, as if it were some objective organization, not a think tank funded by big defense contractors to promote war.
It’s most likely that it is a propaganda drive by the USG to diminish or obscure the impact of the undisputed US bombing of the genuine medical facility in Kunduz.
