It was the launch of an Israeli Patriot PAC-2/GEM anti-air missile against an incoming Syrian air-defense S-200 missile that caused the explosion which rocked the towns between Tel Aviv and Haifa on Monday night. This is reported by US military sources. The intruding Syrian missile came from the Damascus region and was aimed at the IAF F-16I jets conducting raids in that region. By the time it was fired, the Israeli jets raiders were over the Golan on their way back to base. These American-sourced reports contradicted the claims in Israel that the attempted interception was conducted by an IDF David’s Sling anti-air missile battery.
