JERUSALEM (JTA) — Syrian rebels hinted that Israel was responsible for an attack on a naval barracks that destroyed advanced Russian missiles.

A spokesman for the Free Syrian Army’s Supreme Military Council said the early morning attack on July 5 near the port of Latakia originated from long-range missiles fired from a boat in the Mediterranean Sea, Reuters reported.  The spokesman said the firepower was consistent with that of the Israeli military.

Israel has neither confirmed nor denied involvement in the strike, according to Reuters.

Israel has expressed concern during the current civil war that Syrian weapons could fall into the hands of Hezbollah, the Lebanon-based terrorist organization.

Israel allegedly was involved in attacks on Syrian weapon caches in January and May.
