The tragedy at Sandy Hook Elementary School invoked much empathy from Israeli leaders and organizations. Both President Peres and Prime Minister Netanyahu sent condolences. Israel Humanitarian Aid donated boxes of fresh food to first responders in Newtown. And Hadassah has raised funds to plant a grove of 3,000 trees in Beersheva River Park, Israel, in memory of the 26 victims.
