Israel Air Force (IAF) jets were deployed to the northern border with Lebanon after radar detected an approaching unidentified aircraft.

One hour before the Yom Kippur - Day of Atonement - fast ended, the IAF deployed two jets and an attack helicopter to the north to search the area, together with IDF - Israel Defense Forces - ground troops.

The unidentified aircraft turned around, flying back north to Lebanon.

The IDF has been on hightened alert throughout the country, especially in the north because of ongoing threats by Hezbollah to revenge the February assassination of Imad Mughniyeh, the terror group's second in command.

Historically, the Jewish holidays have been a favorite time for Israel's enemies to attack, but with outgoing Prime Minister Ehud Olmert overseeing a caretaker government, the country is even more vulnerable this year.

IDF troops are on high alert for terrorist infiltrations to northern Israeli border communities or for Hezbollah to dispatch an explosives-laden drone into the country.
