Planes over Syria

"Activists said that Syrian security forces used tanks and heavy machine guns in a push to recover the rebel-held districts."  Yesterday, the BBC interviewed a "protester" who insisted that Syrian regime forces are bombing Homs from the air.  But no other sources reported that.   Is there any claim against the Syrian regime that does not get reported and cited?  I mean, if an "activist" told the New York Times correspondent in Beirut that Syrian regime forces dropped a nuclear weapon on Homs, I am sure that the New York Times would dutifully report that on the front page.
