...Syrian forces hit a suburb of Damascus with bombs that rescue workers said unleashed toxic gas...

This explanation makes more sense then Assad deliberately launching a chemical attack when he’s almost won the battle. Same holds true for last “chemical attack”.

Hummm, the wording does not specifically say that the "toxic gas" was contained IN the bombs, just that it was "unleashed".

Did the "leashed" "toxic gas" just happen to be sitting in the Rebel's buildings by coincidence before the bomb were dropped?

This sure beats the heck outa me.
