A Lebanese security official says Israeli warplanes have flown over southern Lebanon.
The official says the flights were seen heading from southern Lebanon toward the eastern Bekaa Valley that borders Syria. He spoke on condition of anonymity in line with regulations.
Israel had no comment.
Friday's flights come two days after officials said Israel launched a rare airstrike inside Syria, targeting a convoy carrying anti-aircraft weapons bound for Hezbollah, the powerful Lebanese militant group allied with Syria and Iran.
The Syrian military denied there was a weapons convoy. It said low-flying Israeli jets crossed into the country over the Israeli-occupied Golan Heights and bombed a scientific research center.
The facility is in the area of Jamraya, northwest of Damascus, about 15 kilometers (10 miles) from the Lebanese border.
