The pro-Iranian Hezbollah movement said on Tuesday it had launched drone attacks at Israeli army targets in northern Israel.
Hezbollah said the attack was in support of the Palestinians in Gaza and had targeted "enemy officers and soldiers while they were in the courtyard of the Yiftah Barracks."
The Israeli army said a number of suspicious aerial objects were identified approaching Israeli territory and intercepted, and others which were not intercepted caused only light damage on the ground.
No injuries were reported, the army said.
In retaliation Israeli warplanes struck targets in the western and eastern sector of south Lebanon.
On Monday two Israeli reservists were killed in a Hezbollah drone strike.
Since the beginning of the Gaza war seven months ago, there have been repeated confrontations on the border between Israel's army and the Hezbollah militia.
