Israeli defense officials say the country is on high alert for possible attacks from the Lebanon-based militant group Hezbollah following an Israeli airstrike on Hezbollah fighters in Syria.
Israeli officials say the country has boosted deployment of its "Iron Dome" aerial defense system along its northern frontier, which borders Lebanon, and has increased surveillance activities in the area. The officials say Israel's Security Cabinet is scheduled to meet Tuesday to discuss a potential escalation in violence.
The officials spoke on condition of anonymity because they were not authorized to discuss security deliberations publicly.
Israel has neither confirmed nor denied Sunday's strike on the Syrian side of the Golan Heights, which killed a prominent Hezbollah fighter, a senior Iranian general, and five other Hezbollah members.
