Hezbollah leader vows 'open war'

The militant group said its leader was unhurt in the attack. It was not clear when his remarks were recorded.

Israel is demanding Hezbollah free two Israeli soldiers. More than 60 Lebanese have been killed in the offensive.

Meanwhile Israel says four soldiers are missing after a naval ship was damaged by a Hezbollah explosive drone.

It is thought to be the first time Hezbollah has used such a weapon.

The ship has now been towed back to Haifa and a search is continuing for the missing men.

Israel says a Hezbollah rocket aimed at one of its ships early on Saturday missed, and hit a civilian ship instead.

'War on every level'

In his address on Hezbollah's TV channel in Lebanon, Sheikh Nasrallah referred to an Israeli warship he said had launched attacks from of the coast of Lebanon, saying: "Look at the warship that has attacked Beirut, while it burns and sinks before your very eyes."
