Prime Minister Benjamin Netanyahu lauded his troops for the swift action at the weekly cabinet meeting without going into details.
"I wish to praise IDF (Israel Defence Forces) soldiers for thwarting an attack on our northern border," Netanyahu told his cabinet colleagues.
The skirmish began when a unit of the IDF Golani Brigade was in the middle of conducting an ambush and crossed the fence while remaining in Israeli territory and came under heavy machine gun and mortar fire from ISIS fighters.
Israeli Air Force claimed to have killed all the four attackers soon after.

"The response was sharp and swift and was intended to send a message that we are in the area and are determined to protect our border. The IDF's response took place within minutes," an army official was quoted as saying by news website 'Ynet'.
"We have no intention of escalating matters in the area but we will not accept a reality in which forces open fire in our direction," he added.
