Hizbullah's Al-Manar television claimed on Monday that guerrillas had hit an IDF warship with missiles off the coast. The IDF denied the claim.
Al-Manar said the strike on the warship off the coast of the southern city of Tyre was part of its retaliation for Sunday's IAF strike in Kana that killed at least 56 civilians.
"This is the beginning of our vengeance for the children of Kana," it said.
The IDF said that "despite all reports in the Arab media," none of its ships were hit. It said all its ships were accounted for.
In July 15, Hezbollah struck a warship off Beirut's coast with what Israel said was an Iranian-made, radar-guided C-802 missile. The strike killed four IDF soldiers.
