Earlier, an explosion targeted an Israeli patrol near the frontier, Hezbollah's Al Manar television reported. Lebanon's LBCI News says that several people were injured in the shelling.
Israeli Defense Force spokesman Brig.-Gen. Moti Almoz told the Jerusalem Post that two heavy armored vehicles, including a D-9 bulldozer, were hit, adding that the explosives were "relatively large."
"We have opened artillery fire, and created a smokescreen to cover the area. We are in control of the incident," Almoz said.
Israeli authorities have asked local residents to remain at home, according to Haaretz.
