The S-300 is an advanced Russian anti-aircraft system. Despite the claims, Russia has apparently not yet supplied Syria with the S-300. The Lebanese military said Israel entered Lebanese airspace in the northern part of the country at 10:45 p.m. Sunday and exited at 11:55 p.m. over the Naqoura area of southern Lebanon.

Other reports said the Latakia blast was related to artillery fire that had no connection to Israel.

Israel has issued repeated warnings that it will not permit the transfer of advanced weaponry from Syria to Lebanon. The Lebanese terrorist group Hezbollah is a close ally of Syrian President Bashar al-Assad’s regime.
