AlQa'dah 2, 1434, Sep 8, 2013, SPA -- Syrian President Bashar al-Assad has denied "that he had anything to do" with the alleged chemical weapons attack near Damascus, dpa cited US broadcaster CBS as reporting Sunday. "There has been no evidence that I used chemical weapons against my own people ... and if, in fact, the [Obama] administration has evidence, then they should show that evidence and make their case," al-Assad was quoted as saying by journalist Charlie Rose, who interviewed him in Damascus on Sunday. The full interview will be broadcast Monday on The Charlie Rose Show on PBS.
