"Our thoughts tonight are with the 21 innocent men and women and their families," Kerry said yesterday during a function hosted by the Israeli advocacy group J Street.
"This certainly bears all the hallmarks of a terrorist attack and we condemn it in the strongest possible terms. These outrages are solely determine to instill fear. They will never succeed in intimidating the Israeli people," Kerry said.
"What this tragedy also does is it also underscores the importance of ending this conflict," he said in his remarks.
