Hello Peter...Yes, there are many events happening currently with resignation of the rebels leader prior to this supposed news of Assad's death or attempted..... Then adding Obama’s visit there, and the soon following rockets from Israel into Syria...one does ponder these events and can arrive at several possibilities of what's happening.
Below video of Israel's rockets hitting Syria....from RT.

The rebel leader that resigned, said the rebels crossed a red line. Obviously that red line was their use of Chlorine Gas in the recent attack. So those supporting the Terrorist Rebels, had to play their last card. Another attempt on Assad’s life.
