Israel has reinforced its units on the northern borders with Syria and Lebanon after a missile attack on army vehicles killed two soldiers on Wednesday.
Hizbollah fired at least five anti-tank missiles at an IDF convoy outside the village of Ghajar, killing Captain Yohai Klangel, 25 and Sergeant Dor Nini, 20. Seven others were wounded.
In retaliation, the IDF struck at Hizbollah targets throughout the border region.
The attack took place in the wake of last week's air strike in which senior Hizbollah commanders and an Iranian general were killed near Israel's Golan border.
