Israeli troops along the border with Lebanon were on high alert Wednesday night after Hezbollah threatened action over what it said was an Israeli air raid, according to AFP and Army Radio.
"The military ordered farmers to stay away from the border... and there was movement of military vehicles around border communities," Army Radio stated. The army itself did not make any statement.
Earlier Wednesday, Hezbollah threatened to retaliate after Israel's first reported air raid targeting a position of the Lebanese Shiite movement since a 2006 war between them.
The terror group vowed revenge on Israel at "the appropriate time, place and means," according to AFP. "This new attack amounts to blatant aggression against Lebanon, its sovereignty and territory," the statement claimed.
The threat came two days after Israeli warplanes reportedly struck a Hezbollah position in eastern Lebanon, amid fears the region might be dragged into further conflict over the Syrian civil war. The strike took place near the town of Nabi Sheet, a bastion of Hezbollah and the suspected site of a Hezbollah weapons storehouse and training camp.
Hezbollah is an ally of Syrian President Bashar al-Assad, and its forces are fighting alongside his against rebels seeking to overthrow him.
Israel has not acknowledged the raid, but officials have confirmed a general policy of interdicting suspected arms deliveries from Syria to Hezbollah.
"We are doing everything that is necessary in order to defend the security of Israel," Prime Minister Binyamin Netanyahu said Tuesday. "We will not say what we're doing or what we're not doing," he said.
