Prime Minister Benjamin Netanyahu said Israel's downing of a Syrian jet on Tuesday was a response to a "gross violation of the 1974 separation agreements between Israel and Syria.""Our air defense systems identified a Syrian Air Force plane, taking off from the Syrian air base T-4 and penetrating Israel. This is a gross violation of the 1974 separation agreements between Israel and Syria. I made it clear that we would not accept any such violation, we would not get any intrusion into our territory, either from the ground or from the air," he said in a statement."Our forces acted accordingly. We insist that Syria strictly respect the separation agreements between us and them."
