Prime Minister Benjamin Netanyahu said Wednesday that Israel views with "great gravity" the latest flare-up on the Lebanese border and pledged a tough response in the event of further incidents.
"We shall react forcefully to any attack against us," Netanyahu said in a statement. "I advise Hezbollah not to test Israel's strength. Hezbollah is once again endangering Lebanon due to its aggression."
Israel and Hezbollah fought a devastating month-long war in 2006.
Israel said earlier it had launched air strikes against Hezbollah observation posts in Lebanon after shots were fired from across the border towards its troops the previous evening.
The border flare-up came hours after Lebanon rejected an Israeli call to reform the UN peacekeeping force which patrols the border ahead of a UN Security Council vote to renew its mandate.
The Israeli army had said earlier that a "security incident" was unfolding near Manara, a kibbutz near the UN-demarcated border between the two countries, and urged residents to take shelter.
It reported no Israeli casualties.
Manara was quiet on Wednesday morning, an AFP journalist reported. The army told residents they could come into the open and resume work in the fields.
