Netanyahu vows 'forceful' response if more attacks from Lebanon

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."

Earlier, Israeli aircraft struck posts belonging to the Lebanese Shi'ite group Hezbollah after shots were fired from Lebanon towards its troops, Israel's military said.

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.

No Israeli troops were wounded in the firing, the military said. Soldiers deployed illumination flares, smoke shells and live fire after the shots from the Lebanese side of the frontier, it said.

"In response, overnight, IDF attack helicopters and aircraft struck observation posts belonging to the Hezbollah terror organization in the border area," the military said in a statement, referring to the Israel Defense Forces.

There was no immediate comment from Hezbollah.

Tension has been running high on the border. Last month, Israel said Hezbollah carried out an infiltration attempt, which the Iran-backed group denied.

The Israeli military said it lifted a curfew it had imposed overnight. Israel and Hezbollah fought a devastating month-long war in 2006 as well.
