Israeli naval missile ships destroyed the Syrian military fleet in an operation on Monday night as part of a broad campaign to eliminate strategic threats to Israel, Defense Minister Israel Katz said on Tuesday, during a visit to a naval base in Haifa. In a statement he said Israeli forces were establishing themselves in the buffer zone between Syria and the Israeli-occupied Golan Heights and said he had ordered a "sterile defensive zone" to be created in southern Syria, without a permanent Israeli presence, to prevent any terrorist threat to Israel.
