The IDF denied on Monday night a Lebanese report that missiles had hit an Israeli warship off the southern coastal city of Tyre.
The missile strike was first reported by Hizbullah's Al-Manar television, which claimed guerillas attacked the ship.
Al-Manar said the strike on the warship was part of its retaliation for an Israeli strike in Kana on Sunday that killed at least 56 civilians. "This is the beginning of our vengeance for the children of Kana," it said.
But 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.
