The army said in a statement carried by the country's official news agency that six Israeli warplanes flew over the border village of Alma al-Shaab and other southern towns and villages for about 30 minutes Friday.
The statement added that six other Israeli warplanes flew over the Mediterranean off the coastal city of Batroun and over other northern towns for about an hour.
There was no immediate statement from the IDF, which usually does not comment on flights over Lebanon.
More than two years after the Second Lebanon War, Israeli-Lebanese tensions remain high. Several weeks ago, IDF Northern Command Chief Gadi Eisenkot told Yedioth Ahronoth that the army would respond in a disproportionate manner against villages from which Hizbullah fires missiles into Israel.
In a later interview published in the United Arab Emirates-based al-Ittihad newspaper, a Hizbullah member said his organization was on the alert. He referred to Israel as "a cardboard country which will be destroyed by resistance fighters, who achieved the grand victory against the entity robbing Palestine's land in the years 2000 and 2006."
The Hizbullah member added that his organization dose not believe Israel will launch an attack against Lebanon. "Israel is frustrated by many internal problems and is incapable of launching a new war against Lebanon," he said.
He went on to say that Major-General Eisenkot's remarks were a "media war."
