Hezbollah chief Hassan Nasrallah on Wednesday warned "Zionist officers and generals" to "watch your heads," in response to a military tour that Israel's defense minister took on the border with Lebanon earlier in the week.

Nasrallah spoke at a rally that was held to honor a Hezbollah leader who had escaped from an Egyptian prison during the country's unrest, and made his way back to Beirut.

Mohammed Youssef Mansour, better known as Sami Chehab, held up a Hezbollah flag and raised his hands in a V-for-victory sign Wednesday during the rally. Mansour was convicted in 2010 along with 25 others of spying for Hezbollah and plotting attacks in Egypt.

Defense Minister Ehud Barak along with incoming Israel Defense Forces Chief Benny Gantz toured the border with Lebanon on Tuesday, where he said that Israel must remain prepared on their northern border.

Nasrallah, who mentioned Barak by name, called on "Islamic resistance fighters" to "be ready for the day that will come when war will be forced on Lebanon."

"The leadership of the resistance will ask them to take control over the Galilee," Nasrallah said, referring to a region in the north of Israel.

Nasrallah's speech was broadcast to a rally commemorating the killing of three Hezbollah leaders, including the 2008 assassination of Hezbollah's top military commander, Imad Mughniyeh, who was killed by a car bomb in the Syrian capital of Damascus.

Hezbollah and its primary patron, Iran, have blamed Israel for Mughniyeh's killing. Israel has denied involvement.

Nasrallah repeated his threats to Israel that Hezbollah will avenge Mughniyeh's assassination.
