Former US envoy to the Middle East Dennis Ross said on Thursday that Israel mustn't negotiate for the release of Cpl. Gilad Shalit, who was kidnapped on Sunday and whose release was the main objective behind the recent IDF incursion into the Gaza Strip. He asserted that negotiations would only bring about more kidnappings. Ross told Israel Radio that the Palestinians must understand that their leaders in Damascus are only making them suffer, while the leaders sit safely in Syria. The former envoy called upon the US to apply pressure on Hamas leader in Damascus Khaled Mashaal.
