A senior Israeli diplomat spoke Monday of “clear evidence based on raw, real and solid material” – not just assessments - that Bashar Assad is using chemical weapons against rebels. He said this information is known to every concerned intelligence agency and none question it. Israel should be more concerned, he said, about chemical weapons leaking from Syria to Hizballah or other terrorist groups which are trying to reach the Israeli border. Their possible acquisition of chemical or conventional weapons which they never before laid their hands on is of great concern to Israel.
