The Lebanese army bombed movements by militants in the desert region of Ras Baalbek.
Also, Syrian warplanes hit militant hideouts near the Lebanese borders.
Spillover from the Syrian conflict has repeatedly jolted neighboring Lebanon.
Militants from al-Qaeda-linked Nusra Front and Islamic State attacked and briefly seized in August the Lebanese border town of Arsal, which is also close to Ras Baalbek, and took a group of soldiers prisoner when they pulled out.
