The head of Lebanon's Hezbollah said on Wednesday that nowhere in Israel would be safe if a full-fledged war breaks out between the two foes, and he also threatened Cyprus and other parts of the Mediterannean.

Hezbollah has been trading fire with Israel for more than eight months in parallel with the Gaza War. On Tuesday, the group published what it said was drone footage of sensitive military sites deep in Israeli territory.

In a televised address on Wednesday, Hezbollah chief Sayyed Hassan Nasrallah said "there will be no place safe from our missiles and our drones" in Israel in the event of a broader war.

The group also had "a bank of targets" that it could target in precision strikes, he said.

Israel "knows that what also awaits it in the Mediterranean is very big...In the face of a battle of this magnitude, it knows that it must now wait for us on land, in the air, and at sea," Nasrallah added.

The group first showed it could hit a vessel at sea by striking an Israeli warship in the Mediterranean during their 2006 war.

Reports by media and analysts have for years indicated that Hezbollah acquired Russian-made anti-ship Yakhont missiles in Syria, after its forces deployed there more than a decade ago to help President Bashar al-Assad fight the country's civil war.

Nasrallah also threatened Cyprus for the first time, accusing it of allowing Israel to use its airports and bases for military exercises.

"The Cypriot government must be warned that opening Cypriot airports and bases for the Israeli enemy to target Lebanon means that the Cypriot government has become part of the war and the resistance (Hezbollah) will deal with it as part of the war," Nasrallah said.

There was no immediate comment from authorities in Cyprus. (Reuters)
